House Democrats know Republicans are looking to divide their caucus by holding a vote Wednesday on a resolution that rejects calls to completely abolish the U.S. Immigration and Customs Enforcement agency. They say they aren’t going to play the GOP’s political game.

Democratic leaders are not formally whipping for or against the resolution, but are urging their members to reject what they say is a political stunt by Republicans and vote “present,” according to a Democratic leadership aide.

House Minority Leader Nancy Pelosi has privately told members that the vote is political so they should do what’s best for their districts, the aide said.

“Our point is this is not a serious effort, nobody should take it as a serious effort,” House Minority Whip Steny Hoyer told said, calling the measure “a political gotcha bill.”

Democrats leaders’ decision not to whip allows members to vote their consciences and their districts, but their suggestion of a “present” vote sends a strong signal that it’s best for the party that if Democrats remain united.
