Rep. Beto O’Rourke (D-TX), who is challenging Sen. Ted Cruz (R-TX), told the Dallas Morning News that President Trump’s performance at a summit with Russian strongman Vladimir Putin merits impeachment. Said O’Rourke: “Standing on stage in another country with the leader of another country who wants to and has sought to undermine this country, and to side with him over the United States – if I were asked to vote on this I would vote to impeach the president.
