Senators complaining that they were left out of the loop on details of the prisoner swap that brought U.S. soldier Bowe Bergdahl back from five years in captivity weren’t interested in explanations offered at a closed-door briefing Wednesday night. Many of them left early.

According to a report by the Huffington Post, many of President Obama’s most outspoken critics did not stay to hear everything administration officials had to say on the trade. Sen. Rand Paul, R-Kentucky, did not attend at all.

Top-ranking Democrats also left early; Senate Intelligence Committee chair Dianne Feinstein, D-California, also admitted she did not stay through the end of the briefing. In an interview with Bloomberg News set to air this weekend, Feinstein said that she has not yet been convinced that there was ”credible threat” on Bergdahl’s life that justified keeping her and other lawmakers in the dark.
