Dreamers will be at the State of the Union. This GOP rep wants them arrested and deported.

Some Democrats (and one Republican) are inviting "Dreamer" immigrants to the State of the Union address Tuesday night, and a GOP congressman is calling for authorities to arrest undocumented immigrants who show up.

Who is calling for the arrests?

Rep. Paul Gosar (R-Ariz.) tweeted Tuesday afternoon that he had contacted U.S. Capitol Police and Attorney General Jeff Sessions, suggesting that they check identification of SOTU attendees to weed out any illegal immigrants.

His Twitter account also had a quote from Gosar:

"Of all the places where the Rule of Law needs to be enforced, it should be in the hallowed halls of Congress," Gosar said. "Any illegal aliens attempting to go through security, under any pretext of invitation or otherwise, should be arrested and deported."

Who is inviting them?

According to The Hill, "dozens" of Democrats are inviting undocumented immigrants who were brought the U.S. as children to the State of the Union, to put a human face on the immigration debate that has persisted since President Donald Trump announced the end of the Deferred Action for Childhood Arrivals program in September.

Republican Rep. Carlos Curbelo of Florida is also bringing a DACA recipient as his guest. He is running for re-election in a district that Hillary Clinton won in the 2016 election.

What has the reaction been?

AshLee Strong, a spokeswoman for House Speaker Paul Ryan (R-Wis.), said Ryan does not endorse Gosar's tweets.

"The Speaker clearly does not agree," Strong said.

Republican Rep. Ileana Ros-Lehtinen of Florida criticized Gosar for his stance.

Currently enrolled DACA recipients are not in danger of being arrested or deported, but once their permits expire, they will be subject to deportation unless Congress passes legislation protecting them or Trump changes his mind and reinstates the Obama-era program.
