Trump again proved his dominance in the GOP by ousting Rep. Thomas Massie, but he has been leading the party into politically perilous territory.

One Republican congressman says he is exploring ways to end the Trump Justice Department’s move to establish a tax-payer fueled “anti-weaponization” fund, a move likely to draw the ire of President Donald Trump.

Sen. Bill Cassidy of Louisiana is the newest member of the club. Just days after losing his primary to a Trump-backed challenger, Cassidy on Tuesday reversed himself on legislation involving the war in Iran and voted with Democrats to rein in U.S. military action.

Brian Fitzpatrick's warning came as Jamie Raskin plans to introduce a bill saying "no Federal funds" may be used for the fund.

Kentucky Rep. Massie is the latest Republican to suffer the wrath of Trump even as the president's ratings sink into dangerous territory for the GOP.

Cassidy, who lost his reelection bid last week, called for leaders who are "steady, not erratic" and "thoughtful, not impulsive."

Votes in the House and Senate this week to halt the military campaign would prove a stunning embarrassment for the president.
