Near universal dismissal of President Donald Trump’s framework for legislation that would grant a pathway to citizenship for 1.8 million “Dreamers” underscores the difficult task for lawmakers racing to strike a deal that has eluded Congress for close to two decades.

Trump’s proposal, which calls for $25 billion to build a U.S.-Mexico border wall and limits on so-called chain migration, isn’t likely to fly in the Senate or the House, albeit for different reasons.

Senate Democrats, who can filibuster any legislation requiring 60 votes to advance, won’t support it because they say it uses Dreamers as a bargaining chip to enact a laundry list of GOP immigration priorities.

“The White House claims to be compromising because the president now agrees with the overwhelming majority of Americans that Dreamers should have a pathway to citizenship,” Minority Whip Richard J. Durbin of Illinois said in a news release Thursday. “But his plan would put the administration’s entire hard-line immigration agenda … on the backs of these young people.”
