Rep. Paul Gosar, R-Ariz., tweeted Monday that he’d asked U.S. Capitol Police to check the IDs of everyone attending President Donald Trump’s first State of the Union address and to arrest any “illegal aliens in attendance.”

"Today, Congressman Paul Gosar contacted the U.S. Capitol Police, as well as Attorney General Jeff Sessions, asking they consider checking identification of all attending the State of the Union address and arresting any illegal aliens in attendance," Gosar, an immigration hardliner, wrote on his Twitter account.

More than two dozen Dreamers — immigrants who were brought to the U.S. illegally as children — are set to attend the speech as guests of Democratic lawmakers, including House Speaker Nancy Pelosi, D-Calif.

A spokeswoman for House Speaker Ryan, R-Wis., told NBC News that Ryan “clearly does not agree” with Gosar’s view.
