The chilly reception came after Trump lashed out on Twitter at Elijah Cummings, a prominent African-American congressman from Baltimore, calling him a "brutal bully" who should concentrate on cleaning up his "disgusting, rat and rodent infested" district rather than criticizing the work of U.S. immigration officers on the Mexican border. Cummings, who chairs the House Committee on Oversight and Reform, has led investigations into Trump and his administration, called him a racist and lashed out at the president's hard-line immigration policies. The powerful congressman responded to Trump's tweets by inviting him to tour the city and observe hardworking residents.

Attendees stand for the national anthem as they wait for President Donald Trump to speak at the 2019 House Republican Conference Member Retreat dinner. Compared with the reception on the streets, Trump was received warmly with chants of "four more years," as he took the stage at the dinner after brief remarks from House Republican minority leader Kevin McCarthy and Minority Whip Steve Scalise.

President Donald Trump speaks. Touting his achievements as president and ripping Democratic presidential hopefuls in more than an hour of wide-ranging comments, Trump also slipped in one jab against the leaders of the city hosting him. "We are going to fight for the futures of cities like Baltimore that have been destroyed by decades of failed and corrupt rule," he said, to loud applause.
