Cotton: I won't commit to an immigration deal just because Trump supports it

"I can’t make that commitment at all," Cotton told NBC's Chuck Todd after he was asked if he would support whatever the president agreed to in the shutdown negotiations. 

"I will evaluate any deal on its merits and what's best for the people of Arkansas and best for our country," Cotton said on "Meet the Press." 

Senate Republicans and Democrats failed to meet a midnight deadline on Saturday to reach a deal to fund the government. 

Democrats rejected funding legislation because it did not contain a fix for the recipients of the Deferred Action for Childhood Arrivals program, while Republicans say Democrats are holding the government hostage. Trump in September said he would end the Obama-era program, which protects young immigrants brought to the U.S. illegally as children, but gave Congress time to come up with a legislative solution.

Cotton has proven to be one of the most vocal immigration hard-liners in the Senate. 

The Arkansas senator and Sen. David Perdue (R-Ga.) have proposed a measure that seeks to end so-called chain migration, which allows U.S. citizens and permanent residents to sponsor family members abroad to come to the U.S.

Lawmakers do not appear to be any closer to reaching a deal on Sunday as nonessential federal workers are set to be furloughed on Monday.
