WASHINGTON — The No. 2 Republican in the House says Congress is “perplexed” about government eavesdropping and wants more answers from the Obama administration.

House Majority Leader Eric Cantor said this morning that Congress enacted legislation authorizing broader information-gathering powers in the wake of the Sept. 11, 2001 terror attacks and it “was done in a constitutional manner.”

But now, Cantor tells CBS “This Morning,” many lawmakers “don’t know what happened and we’ve got to find out.”

The Virginia Republican says lawmakers hope to learn more details in briefings from administration officials on Capitol Hill this week. Cantor notes “Congress is responsible for the oversight of this program” and members of the House and Senate want to know more about it.

He said there should be a prosecution if anyone leaked classified information.
