Washington (CNN)House Homeland Security Committee Chairman Michael McCaul expressed concerns on Thursday the White House isn't doing enough to save hostages abroad.

McCaul, speaking on CNN's The Lead, declined to confirm a report from the Daily Beast that the White House had intelligence on U.S. citizens held by ISIS but acted too late to save them.

But he said there were similar allegations with the death of American journalist James Foley at the hands of ISIS fighters.

"[The accusations are] that we are waiting too long to send in these rescue missions, and that for whatever reason this is getting bottle-necked up in the White House, [which is] having a hard time making any decision," the Republican said.

"I think time is of the essence in these situations to save these hostages, and it's very, very unfortunate what happened to [ISIS hostage Kayla Mueller]. I'm concerned they're not doing enough not only to save these hostages but to win this war," McCaul sais. "All we're seeing is a policy of containment."
