There's been a holdup on Capitol Hill in advancing the renewal of a program that lets U.S. spy agencies pore over foreigners’ calls, texts and emails. House Republican leaders hoped to advance the legislation Wednesday, but an initial procedural step has been delayed. Rank-and-file members have pushed back despite a pressure campaign that included a trip to the White House and direct involvement from CIA Director John Ratcliffe. A key part of the Foreign Intelligence Surveillance Act allows American spy agencies to collect and analyze overseas communications without a warrant. The program expires Monday. Critics want changes to safeguard Americans’ communications.
