Reps. Mike Lawler and Josh Gottheimer, who are on the House Problem Solvers Caucus, have both been working to tide the rise of antisemitism in the U.S. Lawler, who recently was subjected to an antisemitic comment by Sen. Rand Paul's son, told "Face the Nation with Margaret Brennan" that "the idea that people feel it's okay to engage in that type of conduct is shameful."
