The war between the Democrats and President Trump escalated Monday with an announcement by House Speaker Nancy Pelosi that she’ll call up a resolution condemning the president’s weekend remarks about a small group of minority freshmen women.

“Let me be clear, our Caucus will continue to forcefully respond to these disgusting attacks,” the California lawmaker said in a letter to her Democratic colleagues Monday. “The House cannot allow the President’s characterization of immigrants to our country to stand. Our Republican colleagues must join us in condemning the President’s xenophobic tweets.”
