President Trump’s view that surging family separations at the U.S. border are a valuable negotiating tool is likely to be challenged when he meets with House Republicans on Tuesday to discuss competing immigration bills, including one that aims to end the practice of removing minors from their parents’ custody while they face prosecution for illegal entry.

Most members expect the emotionally charged issue to be brought up during Tuesday’s meeting, according to a House GOP aide closely involved in immigration talks. Depending on the president’s response, Republicans could emerge breathing a sigh of relief of increasingly worried about their party’s prospects in November.
