A measure by GOP Rep. Thomas Massie to cut off U.S. assistance to Israel has sparked a rare division by the chamber’s No. 1. and No. 2 Democrats, Hakeem Jeffries and Katherine Clark.

There’s a big split between Democratic leadership and the base of the party.

House Minority Leader Hakeem Jeffries (D-NY) said in a letter to his caucus that he will oppose an amendment aiming to cut off aid to Israel.

House Minority Whip Katherine Clark’s (D-MA) support for the amendment puts her at odds with House Minority Leader Hakeem Jeffries (D-NY).
