LITTLE ROCK, Ark. (Arkansas Times) — American Atheists have sued Republican Sen. Jason Rapert in federal court for his practice of blocking critics from his Facebook and Twitter accounts.

The lawsuit contends the blocking is a violation of the U.S. Constitution and state law. It contends people were blocked for expressing different viewpoints on his official social media accounts and also because the plaintiffs were atheists.

Matt Campbell of Little Rock is the lawyer in the case. He is also the man behind Blue Hog Report, a muckraking website. Said Campbell:

“Senator Rapert’s own comments demonstrate that his actions were motivated by animus toward atheists and those who support the constitutional separation of religion and government.”

The suit seeks access to Rapert’s public forums, nominal damages, punitive damages and attorney fees.

Note: There’s no U.S. Supreme Court precedent yet on politicians’ blocking people, but trial courts have found disfavor with the practice, including with Donald Trump’s blocking of people from his Twitter account.

Sen. Rapert has defended his actions at times as being actions on personal rather than official accounts.
