Sen. John McCain John Sidney McCainMomentum growing among Republicans for Supreme Court vote before Election Day McConnell urges GOP senators to 'keep your powder dry' on Supreme Court vacancy McSally says current Senate should vote on Trump nominee MORE (R-Ariz.) on Sunday called for a comprehensive plan in response to President Trump's decision to end the Deferred Action for Childhood Arrivals (DACA) program.

During an interview on CNN's "State of the Union," McCain was asked if he thinks Congress should codify DACA and if he thinks there should be a path to citizenship for the DACA recipients.

"I think yes and yes," McCain said. "But I think it ought to be done in a comprehensive fashion."

McCain added it isn't "conscionable to tell young people who came here as children that they have to go back to a country that they don't know."

"There is 900 of these Dreamers that are serving in uniform in the United States military," he said.

"Are we going to go to a young man or woman serving in Afghanistan or Iraq today, and say, 'Hey by the way, you're a Dreamer, get back to fill-in-the-blank?'" he asked.

"We're not going to do that to these young men and women who are serving in uniform."

The country needs a "comprehensive plan," he said.

"We need it to go through Congress, which is what DACA did not," McCain said. "And we did it once in the Senate, we can do it again in a bipartisan fashion."

The Trump administration announced last week it was ending the Obama-era program that protected some immigrants who came to the country illegally as children from deportation.
