WASHINGTON — Two Colorado lawmakers this weekend plan to join a growing swell of politicians headed to the Texas border to get a firsthand look at the way U.S. authorities treat migrant families. U.S. Reps. Diana DeGette, D-Denver, and Mike Coffman, R-Aurora, both tout their trips as fact-finding missions aimed at gathering more information about the Trump administration’s controversial policy of separating families who are caught trying to illegally enter the U.S. “I think it’s important to see for myself,” Coffman said in an interview outside Capitol Hill. But the separate visits by DeGette and Coffman also have raised eyebrows among their political opponents, who see an electoral bent to the excursions.
