The pivotal question presented by this appeal is whether speech of elected state and local government officials made pursuant to their official duties, like speech of non-elected public employees, is less protected by the First Amendment than other speech. The district court held that the First Amendment affords absolutely no *518 protection to speech by elected officials made pursuant to their official duties. We disagree. The First Amendment’s protection of elected officials’ speech is full, robust, and analogous to that afforded citizens in general. Furthermore, when a state seeks to restrict the speech of an elected official on the basis of its content, a federal court must apply strict scrutiny and declare that limitation invalid unless the state carries its burden to prove both that the regulation furthers a compelling state interest and that it is narrowly tailored to serve that interest. In the present case, because the district court dismissed the elected officials’ challenge to a state statute that regulates their speech on the basis of its content without applying the required strict scrutiny analysis, we reverse the district court’s judgment and remand the case for the performance of that task.
I.
The plaintiffs, elected city council members, were indicted in state court for violations of the criminal provisions of the Texas Open Meetings Act (“TOMA”)
1
by acting as a quorum in exchanging private emails discussing whether to call a council meeting to consider a public contract matter. After prosecuting the charges for several months, the district attorney dismissed them without prejudice. The plaintiffs, alleging fear of future prosecutions and undue restriction of their First Amendment speech rights, brought this § 1983 action in federal district court for declaratory and injunctive relief against the state attorney general and the district attorney, challenging as content-based speech regulations the criminal provisions of TOMA. The district court dismissed the plaintiffs’ claims, holding that under
Garcetti v. Ceballos,
II.
• Defendants assert that this case is nonjusticiable because the plaintiffs lack standing and them claims are moot. We agree with the district court that the plaintiff Mr. Rangra has standing, and we conclude that the case is not moot. 2
To establish standing, the plaintiff must demonstrate injury, causation, and redressability.
See Lujan v. Defenders of Wildlife,
“The standard — encapsulated in the phrase ‘credible threat of prosecution’ — is quite forgiving.” 3 “[W]hen dealing with ... statutes that facially restrict expressive activity by the class to which the plaintiff belongs, courts will assume a credible threat of prosecution in the absence of compelling contrary evidence.” 4
The district court held that the plaintiff established standing by demonstrating injury in fact, causation, and redressability through self-censorship out of fear of prosecution under TOMA.
5
We agree. The plaintiffs affidavits and trial testimony show that he has self-censored his speech to avoid prosecution under TOMA
6
and thereby established injury.
7
Moreover, the plaintiff has alleged threats of prosecution that cannot be characterized as “imaginary or speculative.”
See Steffel,
Because the reasons for the plaintiffs standing continue to exist, we also reject defendants’ argument that the case is moot. 9
III.
The plaintiffs challenge the criminal provisions of TOMA as state regulations imposing an invalid content-based restriction of free speech. 10 The Supreme Court has held that the strict scrutiny test governs challenges for assessing laws that regulate speech on the basis of its content. 11
Strict scrutiny, a formula crafted by the Supreme Court for implementing constitutional values, is one of the most important elements of modern constitutional law. 12 Strict scrutiny varies from ordinary scrutiny by imposing three hurdles on the government. It shifts the bur *521 den of proof to the government, requires the government to prove that its action or regulation pursues a compelling state interest, and demands that the government prove that its action or regulation is “narrowly tailored” to further that compelling interest. 13
We agree with the plaintiffs that the criminal provisions of TOMA are content-based regulations of speech that require the state to satisfy the strict-scrutiny test in order to uphold them.
14
A speech regulation is content-based if it defines the regulated speech by reference to its content.
15
For example, in
Burson v. Freeman,
Furthermore, because TOMA imposes a content-based regulation, we conclude that the district court was required to apply the strict-scrutiny test and to make the state carry its burden of proving that the statute pursues a compelling interest which the law is narrowly tailored to further. The district court did not perform that task because it mistakenly concluded that elected officials’ speech made pursuant to their official duties is totally unprotected by the First Amendment. For this reason, the district court dismissed the plaintiffs’ claims as not actionable without ever undertaking the strict-scrutiny analysis. Consequently, we must vacate the district court’s judgment and remand the case to it for a proper application of the strict scrutiny test. Before doing so, however, we will explain why the district court erred in assuming that the speech of elected officials made pursuant to their official duties is entitled to no protection under the First Amendment.
IV.
The Supreme Court, in Garcetti, held that the First Amendment does not protect a government employee from discipline based on speech made pursuant to the employee’s official duties. 17 The district court assumed that there is no meaningful distinction between the speech of elected officials and that of public employees and held that, under Garcetti, the plaintiffs’ speech pursuant to their official duties was not protected by the First Amendment.
The district court’s premise that the First Amendment’s protection of elected officials’ speech is limited just as it is for the speech of public employees, however, is incorrect. Job-related speech by public employees is clearly less protected than other speech because the Court has held that government employees’ speech rights must be balanced with the government’s need to supervise and discipline subordinates for efficient operations. 18 The First Amendment does not protect government employees’ job-related speech unless the speech is about a matter of public concern, “and even then, a government employee may be fired or disciplined for her speech if the government employer can show, on balance, that the efficient operation of the office justified the action.” 19 But when the state acts as a *523 sovereign, rather than as an employer, its power to limit First Amendment freedoms is much more attenuated. 20 That is because a state’s interest in regulating speech as sovereign is “relatively subordinate ... [as] [t]he government -cannot restrict the speech of the public at large just in the name of efficiency.” 21 Garcetti itself, like the Court’s other public employee speech cases, recognizes the state’s very limited power as sovereign to infringe on First Amendment freedoms. 22 None of the Supreme Court’s public employee speech decisions qualifies or limits the First Amendment’s protection of elected government officials’ speech. 23 Contrary *524 to the district court’s reasoning, there is a meaningful distinction between the First Amendment’s protection of public employees’ speech and other speech, including that of elected government officials.
Indeed, the Supreme Court’s decisions demonstrate that the First Amendment’s protection of elected officials’ speech is robust and no less strenuous than that afforded to the speech of citizens in general. For example, in the 1960s the Court held in
Bond v. Floyd,
.Recently, in
Republican Party of Minnesota v. White,
Most significantly, this court in
Jenevein v. Willing,
*526 In Jenevein, we expressly declined the parties’ invitation to draw upon the “Pickering-Garcetti line of cases for sorting the free speech rights of employees elected to state office.” 27 We noted that those cases’ “categorical divisions of public and private speech fail to illuminate the state’s interest in constraining speech by an elected public official, political speech at the core of the First Amendment, and its necessity.” 28 Further, we noted that an elected official’s relationship with the state differs from that of an ordinary state employee, observing “[o]ur ‘employee’ is an elected official, about whom the public is obliged to inform itself, and the ‘employer’ is the public itself, at least in the practical sense, with the power to hire and fire. It is true that [the elected official] was an employee of the state. It is equally true that as an elected holder of state office, his relationship with his employer differs from that of an ordinary state employee.” 29
Conclusion
Applying the foregoing precepts, we conclude that the district court incorrectly assumed that the Pickering-Garcetti line of decisions, rather than the strict scrutiny test as elaborated in White, governs the present case. Accordingly, we reverse the district court’s judgment and remand the case to it for the application of the strict scrutiny formula to Tex. Gov’t Code § 551.144. 30 In doing so, we point out, however, that the Supreme Court has rejected “the notion that strict scrutiny is ‘strict in theory, but fatal in fact.’ ” 31 The *527 fact that strict scrutiny applies ‘“says nothing about the ultimate validity of any particular law; that determination is the job of the court applying’ ” that standard. 32
For these reasons, the judgment of the district court is reversed and the case is remanded to it for further proceedings consistent with this opinion.

Because of Mr. Brown’s prosecution of me and my fellow councilors, I am afraid to do this. I am afraid to exercise my First Amendment rights to communicate with my fellow councilors, and the public. I am afraid that if I talk to anyone about public matters, except at a city council meeting, I could be indicted and face a criminal prosecution. This threat to me is ongoing and real. But for this threat, I would exercise my First Amendment rights to communicate with the voters and public officials.

Garcetti
did not expand the scope of the public employee speech limitations to include elected officials; rather,
Garcetti
merely carved out a narrow exception to the Supreme Court’s holdings that a government employer may not discipline or adversely affect public employees for their speech involving matters of public concern unless the state can prove that the needs of the government outweigh the speech rights of the employee. In
Garcetti,
Ceballos, a deputy district attorney, alleged that he had been subjected to adverse employment actions in retaliation for engaging in protected speech, viz., for writing an internal memo recommending the dismissal of a criminal case on the basis of alleged governmental misconduct.
See Garcetti,
While Garcetti added a new qualification of public employees' freedom of expression recognized by the Court’s long line of cases concerning public employee speech rights, it did nothing to diminish the First Amendment protection of speech restricted by the government acting as a sovereign rather than as an employer and did nothing to impact the speech rights of elected officials whose speech rights are not subject to employer supervision or discipline.
. Even before
White,
however, as evinced by the two principal decisions upon which it relied, the Court had vigorously applied the First Amendment protections through the strict scrutiny test on behalf of elected officials, candidates for elective offices, and political parties.

We emphasize that we remand this matter for the district court to conduct a strict scrutiny review in the first instance because that inquiry might well require development of the record beyond its present state, as the state has not yet been afforded an opportunity to prove that TOMA § 551.144 is narrowly tailored to further a compelling state interest. TOMA § 551.144 may indeed survive this strict scrutiny inquiry. Numerous states apparently employ similarly tailored provisions in their open meetings acts. See Ann Taylor Schwing, Open Meeting Laws 2d 275, 285 (2000). However, we simply lack the record necessary to make a strict scrutiny determination here; thus we remand the issue.
