TOPEKA, Kan. — First District Congressman Roger Marshall toured several immigrant detention sites in the McAllen, Texas, area. He says the trip re-solidified his support for President Donald Trump’s border wall proposal.

His assessment differs from the one reached by Democrats who this week visited separate facilities in the El Paso area.

A report released Tuesday by Department of Homeland Security Acting Inspector General Jennifer Costello raised concerns of overcrowding at some of the same McAllen area facilities Marshall visited.

Marshall traveled to Texas as a member of the “Doc Caucus,” a group of Republican doctors in Congress. He has said he might run for U.S. Senate.
