Opinion for the Court filed by Circuit Judge ROGERS.
John E. Settles appeals the dismissal of his second amended complaint against the United States Parole Commission for lack of standing. Settles contends that the district court erred in ruling that he failed to show an injury in fact because, in order to vindicate a procedural right, he was not required to establish that the right, if vindicated, would lead to a favorable outcome. Upon de novo review, we agree that Settles has standing to bring (1) a claim under 42 U.S.C. § 1983 (2000), alleging that he was denied equal protection because the Commission’s rule and policies, preventing him from having a representative at his parole hearing, did not equally apply to federal prisoners who were seeking to be paroled, and (2) a challenge to the Commission’s rule under the Administrative Procedure Act (“APA”), 5 U.S.C § 706 (2000). However, we hold that because he has sued the Commission and not the individual members of the Commission, Settles has asserted a claim against an entity that enjoys sovereign immunity from suit under § 1983, and thus the court lacks jurisdiction over his § 1983 claim. Because the district court considered Commission materials beyond the pleadings, the dismissal of the § 1983 claim can also be viewed as the grant of summary judgment. Accordingly, we affirm the grant of summary judgment to the Commission on the § 1983 claim, and because Settles’s APA claim fails on its merits, we direct the entry of summary judgment for the Commission on the APA claim.
I.
As part of the National Capital Revitalization and Self-Government Improvement Act of 1997 (“Revitalization Act”), Pub.L. No. 105-33, §§ 11000-11723, 111 Stat. 251, 712-87 (1997), Congress required the Commission to “assume the jurisdiction and authority of the Board of Parole of the District of Columbia to grant and deny parole, and to impose conditions upon an order of parole, in the case of any imprisoned felon who is eligible for parole or reparole under the District of Columbia Code” (hereafter “D.C.Code offenders”). Revitalization Act § 11231(a)(1),
The Commission’s regulations in effect at Settles’s parole hearing on June 27, 2000, provided that:
A prisoner appearing for a parole hearing in a federal facility may have a representative pursuant to [28 C.F.R.] § 2.13(b). A prisoner appearing for a parole hearing in a facility other than a federal facility shall not be accompanied by counsel or any other person (except a staff member of the facility) except in such facilities as the Commission may designate as suitable for the appearance of representatives.
Amended Interim Rule, 65 Fed.Reg. 19,-996, 19,997 (Apr. 13, 2000) (amending 63 Fed.Reg. 39,172, 39,177 (July 21, 1998)) (emphasis added). The Final Rule, which was promulgated a month after Settles’s parole hearing, was identical to the Amended Interim Rule, except that it clarified that the term “federal facility” included “federal contract facilities.” Final Rule, 65 Fed.Reg. 45,885, 45,888 (July 26, 2000) (codified at 28 C.F.R. § 2.72(c) (2001)).
Settles was not permitted to have a representative present at his June 2000 parole hearing because he was a D.C.Code offender incarcerated at the Corrections *1101 Corporation of America prison in Youngstown, Ohio, which is a D.C. contract facility that had not been designated suitable for representatives. He was denied parole in August 2000, and his next parole hearing is scheduled for April 2006. He filed a pro se petition for habeas corpus against the Commission, and the district court, in denying the Commission’s motion to transfer venue, construed Settles’s petition as a § 1983 complaint and appointed counsel. Counsel, by leave of court, filed two amended complaints against the Commission, each alleging that the regulation preventing D.C.Code offenders housed in facilities under contract with the D.C. Department of Corrections from having representatives at their parole hearings violates 42 U.S.C. § 1983 and the APA, 5 U.S.C. § 706(2). The amended complaints sought a declaratory judgment invalidating the regulation and injunctive relief in the form of a new parole hearing that “included the opportunity to have a representative” present. The Commission answered, asserting that the complaint failed to state a claim, that venue was improper, and that there was a lack of subject matter jurisdiction, while generally denying the allegations of the APA claim. The Commission, in moving to dismiss the complaint under Fed.R.Civ.P. 12(b)(1) or 12(b)(6), or for summary judgment under Fed.R.Civ.P. 56, as well as in its response to Settles’s motion for summary judgment, challenged Settles’s equal protection claim on the merits and did not raise any statutory defenses or invoke sovereign immunity-
The district court granted the Commission’s Rule 12(b)(1) motion to dismiss for lack of standing, reasoning upon considering the parties’ stipulated facts and certain exhibits submitted by the Commission that Settles had not identified a cognizable injury in fact. The court summarily denied Settles’s motion for summary judgment. Settles appeals, and this court reviews
de novo
both the dismissal for lack of standing,
Nat’l Wrestling Coaches Ass’n v. Dep’t of Educ.,
II.
The “irreducible constitutional minimum of standing” requires that Settles demonstrate that he has suffered an injury in fact, that there is a causal connection between the injury and the conduct complained of, and that it is likely that the injury will be redressed by a favorable decision.
Lujan v. Defenders of Wildlife,
To demonstraté an injury in fact for an equal protection claim,
[w]hen the government erects a barrier that makes it more difficult for members of one group to obtain a benefit than it is for members of another group, a member of the former group seeking to challenge the barrier need not allege that he would have obtained the benefit but for the barrier in order to establish standing. The “injury in fact” in an equal protection case of this variety is the denial of equal treatment resulting from the imposition of the barrier, not the ultimate inability to obtain the benefit. ...
Northeastern Fla. Chapter of Assoc. Gen. Contractors of Am. v. City of Jacksonville,
The Commission’s contrary views are unpersuasive. Its first response is that, even in situations where a plaintiff seeks to challenge a barrier to a benefit, “the plaintiff must still give evidence that he would have been able to exercise the benefit had it been available.” This statement confuses what the “benefit” is: the benefit is not representation; it is receiving parole. The barrier to obtaining the benefit is the prohibition on representation. The Commission maintains that Settles has not satisfied the “able and ready” standard from
Northeastern Florida,
The Commission’s second response is that Settles has not alleged an equal protection injury because he has not alleged that similarly situated individuals were treated differently. Relying on
Koyce v. United States Board of Parole,
Finally, regarding the other prongs of the standing analysis, the Commission’s suggestion that causation is lacking unless its decision to deny Settles parole is fairly traceable to his lack of representation misunderstands the nature of the injury, which is the denial of representation and not the denial of parole. Furthermore, the Commission’s position is contrary to the Supreme Court’s approach to standing in
Northeastern Florida^
where it. held that a plaintiff in Settles’s position “need not allege that he would have obtained the benefit but for the barrier.”
To show injury in fact under the APA, Settles must show that the procedural right to have representation at his parole hearing is connected to his injury.
Sugar Cane Growers Coop. v. Veneman,
The Commission devotes only a footnote in its brief to challenging Settles’s standing to bring the APA claim, and both of its arguments lack merit. First, without authority, the Commission asserts that if Settles is not “able and ready” then he does not have standing. As established above, assuming such a requirement applies, he is “able and ready.” Second, the Commission contends that the fact that he was treated similarly to others in his class defeats standing. This is not so because Settles does not solely challenge the classification of D.C.Code offenders in D.C. contract facilities compared to those in federal facilities; ■ rather, he mainly contends on appeal that the regulation is arbitrary and not supported by substantial evidence because it fails to distinguish between D.C. contract facilities and District facilities.
For these reasons, we hold that Settles has standing and we turn to the § 1983 and APA claims set forth in the second amended complaint.
III.
Section 1983 permits suit against a “person” acting under color of State or District of Columbia law.
See, e.g., Williams v. United States,
A.
To recover under § 1983, the plaintiff must show that the defendant was acting “under color” of state law. Section 1983 does not apply to federal officials acting under color of federal law.
See Williams,
However, by failing to raise its statute-based challenges in the district court, including that it is not a “person” under § 1983, the Commission has waived these issues. “[A]s a matter of prudence if not jurisdiction, claims neither raised nor addressed below usually may not be heard on appeal.”
Nat’l Fed’n of Fed. Employees v. Greenberg,
B.
The Commission’s assertion of sovereign immunity, however, goes to this court’s jurisdiction and may properly be raised at any time.
See Brown v. Sec’y of Army,
A waiver of the United States’s sovereign immunity must be unequivocally expressed in statutory text,
see, e.g., United States v. Nordic Village, Inc.,
Nor does § 11231(a)(1) of the Revitalization Act,
C.
Although sovereign immunity blocks a § 1983 claim against the Commission, Settles urges that his complaint be liberally construed as naming the individual members of the Commission as defendants. He points to
Fletcher I,
in which the court construed a
pro se
complaint against the Commission’s members “in accordance with the general rule that, upon a motion to dismiss, the complaint — particularly a complaint filed by a pro se prisoner — should be construed liberally.”
It is certainly true that complaints are to be liberally construed at the stage of a motion to dismiss. However, in stating the general rule, the court in
Warren
was focusing on the factual allegations stated in a complaint. This is clear because the court acknowledged that courts sometimes reach further than the complaint in
pro se
cases to discern the facts necessary to state a cause of action.

It is long settled that the United States cannot be sued without its consent.

Part III.B,
supra.
To the extent that it may not have been entirely clear in what capacity the Commission acted when it denied Settles a representative at his parole hearing — because it was acting under District of Columbia law and in .fact applied a rule that was identical to that of the former D.C. Parole Board — counsel would have been alerted to the need to address who is the proper defendant. Although Settles’s counsel did not have the benefit of our decision in
Fletcher I
when he filed the second amended complaint, there was no law in this circuit or others suggesting the Commission could be sued as a “person” under § 1983, and what law there was suggested it could not. In
Al Favad v. CIA
Thus, it was eminently foreseeable that the Commission would, at some point, advance both jurisdictional and statutory defenses. The fact that Settles’ second amended complaint was virtually identical to his first amended complaint — there was only a single repeated citation error (what appears to be a typographical error) citing 28 U.S.C. § 2.73(c) instead of § 2.72(c)— does not change the analysis, because the rule of liberality extends, except as applied in Fletcher I, to factual allegations as distinct from renaming the defendant in order to avoid an immunity defense. Cf. 5B Wright & Miller, Federal Praotioe AND Procedure: Civil § 1357, at 722. Otherwise, Fletcher I would establish a rule of party substitution, which would suggest that the Commission could never succeed in a motion to dismiss -on the ground of sovereign immunity.
In any event, the procedural posture of this case indicates that there is no legal basis to construe Settles’s second amended complaint to name the individual Commissioners as defendants. When a court rules on a Rule 12(b)(1) motion, it may “undertake an independent investigation to assure itself of its own subject matter jurisdiction.”
Haase v. Sessions,
IV.
Both parties claim they are entitled to summary judgment on Settles’s APA claim. No material facts are in dispute, so we inquire whether either party is entitled to judgment as a matter of law. Settles contends that the Commission’s Amended Interim Rule was arbitrary and not supported by substantial evidence because of the absence of a connection between the facts found (lack of staffing and security for representatives to attend parole hearings in District facilities) and the choices made (prohibiting representation at both District facilities and D.C. contract facilities). He cites several passages from Commission meetings and the Federal Register in support of his argument that the regulation swept too broadly when the evidence before the Commission indicated only that there were resource problems in District facilities and not. in D.C. contract facilities.
The Commission is entitled to summary judgment if the path of its reasoning is sufficiently discernable in light of the record.
See Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co.,
During the Commission’s quarterly business meeting, the Commission’s General Counsel stated that, because it was not clear that each of the facilities was “set up security-wise to allow in representatives,” prior review should be required before representatives were allowed. The General Counsel observed that “I think it’s going to have to go on a case-by-case basis because much of it depends on the physical layout of the facility where parole hearings are being held and what the arrangement between that facility and the Bureau of Prisons is.”
Settles emphasizes that the evidence in the record demonstrates that the prohibition of representatives was based on the lack of resources in prison facilities operated by the D.C. Corrections Department. This is not so, although Settles is correct that the Amended Interim Rule was an outgrowth of a policy instituted because of a lack of resources at the D.C. Corrections Department. The General Counsel addressed D.C. contract facilities in his remarks to the Commission. Also, Settles’s brief suggests that there was a blanket prohibition on representatives in parole hearings held in D.C. contract facilities. Again, not so. D.C. contract facilities required prior approval of the Commission before representation was permitted. See Amended Interim Rule, 65 Fed.Reg. at 19,997. At the time of Settles’s parole hearing, which was approximately two *1109 months after the Amended Interim Rule was effective, the Commission had not approved the presence of hearing representatives in the facility in which he was housed. Settles offers nothing to indicate that the Commission’s failure to approve the presence of representatives at the Youngstown facility by the time of his June 2000 parole hearing was arbitrary or otherwise unlawful.
Because the Commission was concerned about resource constraints at the relevant facilities and received comments on the restriction of representatives, the record reveals the required “rational connection between the facts found and the choice made.”
Bowman Transp.,
Accordingly, we hold that Settles has standing to bring his § 1983 and APA claims. We further hold that the court lacks jurisdiction over Settles’s § 1983 claim, and because the district court considered Commission exhibits in dismissing the § 1983 claim, we affirm the grant of summary judgment to the Commission on the § 1983 claim. Finally, we hold that Settles’s APA claim fails on the merits and we direct the entry of summary judgment for the Commission on the APA claim.
