Dozens of Democrats and one centrist GOP lawmaker are bringing such immigrants as their guests to the State of the Union amid the debate in Congress over whether they should be allowed to stay in the country.

"The Speaker clearly does not agree," Ryan spokeswoman AshLee Strong said in response to Gosar's tweets.

Many of the young immigrants who are guests to Tuesday night’s State of the Union are recipients of the Obama-era Deferred Action for Childhood Arrivals (DACA) program, which the Trump administration is rescinding.

Roughly 700,000 qualifying immigrants received temporary work permits through DACA. They are at risk of deportation on a rolling basis as their permits expire over time unless Congress acts on a permanent fix or if Trump were to reinstate the program.

Democrats have brought Dreamers to joint addresses to Congress in the past. And Gosar isn’t the first Republican to object to their presence in the House chamber.

Those with current DACA enrollment status reside in the U.S. legally and are not at risk of arrest or deportation if they attend the State of the Union on Tuesday night.

A spokeswoman for the Capitol Police did not immediately respond to request for comment.

"Oh my goodness, RepGosar. Dreamers don’t pose a threat to us. This is so drastic and cruel. Dios mío," Ros Lehtinen tweeted.

Trump is expected to address immigration at some point in his address Tuesday night. The White House last week unveiled an immigration framework that would grant nearly 2 million immigrants brought to the U.S. illegally as children a path to citizenship, in exchange for $25 billion to build Trump’s promised wall along the Mexican border and new limits on legal immigration.

Trump’s guests do not include any such immigrants who would be granted citizenship under his proposal. Instead, Trump has invited parents of girls killed by the gang MS-13, as well as an Immigration and Customs Enforcement special agent in charge of investigations that have led to arrests of MS-13 members.
