Republicans are attempting to curtail the powers of the Department of Homeland Security (DHS) after it purportedly engaged in substantial social media censorship.

The DHS’s Cybersecurity and Infrastructure Security Agency (CISA) likely violated the First Amendment by telling social media platforms how to moderate content, a Fifth Circuit federal appeals court recently found. Republicans on the Senate Homeland Security Committee are pushing legislation to address CISA’s ability to collaborate with tech companies to censor content, introducing bills to mandate transparency and accountability regarding CISA’s activities.

“CISA has blatantly violated the First Amendment and colluded with big tech to censor the speech of ordinary Americans,” Republican Kentucky Sen. Rand Paul told the Daily Caller News Foundation. “Federal courts have ordered CISA to stop, but the trust CISA has abused cannot be restored until the agency gives a full accounting of what it has done, and Congress changes the law to create severe penalties for anyone who tries to do the same thing in the future.”

Paul says he will not back cybersecurity bills until CISA earns back Americans’ trust, The Washington Post reported. He also introduced a bill called the Free Speech Protection Act. — The Daily Caller
