Nearly 200 Democratic lawmakers, including House Minority Leader Nancy Pelosi, have filed a lawsuit alleging that President Donald Trump has violated the Constitution’s “foreign emoluments clause” by retaining interest in his business empire.

Thirty members of the Senate Democratic caucus are among the signatories to the legal effort, along with 166 House members. Sen. Richard Blumenthal, D-Conn., and House Judiciary Ranking Democrat John Conyers Jr., are the leaders of the effort.

In addition to Pelosi, other senior Democratic leaders on board include House Minority Whip Steny H. Hoyer of Maryland and his Senate counterpart Richard J. Durbin of Illinois.

Among those not listed as a party to the court filing obtained by CQ Roll Call is Senate Minority Leader Charles E. Schumer, D-N.Y.

The members filing suit contend that they have standing because the president’s business ventures are accepting foreign money without the consent of Congress.
