Washington (CNN) - We can keep your secrets just fine, Mr. President.
That's the message Sen. Dianne Feinstein conveyed to reporters Sunday, responding to questions about whether President Barack Obama's decision not to inform Congress about swapping five Taliban detainees at Guantanamo Bay, Cuba, for U.S. Army Sgt. Bowe Bergdahl had any merit.
In explaining his decision, Obama said the exchange "required no publicity," implying that the legislative branch couldn't be trusted with word of an impending deal to recover Bergdahl, whom the Taliban had held since 2009.
The National Defense Authorization Act requires the administration to provide 30 days' advance notice to Congress of a transfer of Guantanamo detainees.
"We're briefed all the time on operations one way or the other," Feinstein said. "We keep to ourselves."
She added, "There are no leaks."
Feinstein, who chairs the Senate Intelligence Committee, also expressed doubts about the administration's assertion that Bergdahl's life would have been put in danger had news of the deal gone public. Sen. Angus King, an independent from Maine, told CNN last week that defense officials informed senators during a classified briefing that "there was a reasonable chance Bowe Bergdahl would have been killed" had the negotiations leaked.
Feinstein said she was not aware of any evidence indicating such a possibility. “I've heard of none," she said. "I'll put it that way."
The White House also justified its move by saying Bergdahl's health was rapidly declining. Senators were shown a video of Bergdahl, which the administration has said shows the soldier's deteriorating condition. Those who attended the briefing left with mixed opinions, with some saying Bergdahl looked sick while others speculated he was drugged.
Feinstein, however, said Bergdahl’s improvement since his May 31 handover to American forces and subsequent hospitalization at a U.S. military facility in Germany leads her to believe his condition was not life-threatening.
"I think his rapid recovery, which seems to be happening, which I'm grateful (for), indicates that perhaps he wasn't close to death," she said.
