Reuters - Members of the U.S. Congress complained on Tuesday that President Donald Trump�s administration has not shared enough information with them as tensions flared with Iran, with even some Republicans saying they have been left in the dark.

�I think all of us are in the dark over here,� Republican Senator Lindsey Graham told reporters outside the Senate. Asked if he thought lawmakers would be briefed on the situation, he said, �I hope so.�

Nancy Pelosi, the Democratic Speaker of the House of Representatives, has requested a briefing for House members, but an aide said the administration had not yet agreed.

Senate aides said no briefing had yet been scheduled for the full Republican-controlled Senate, despite appeals from Democrats.

�If Iran is responsible for targeted attacks on our service members stationed around the region or any of our national security assets, we should of course respond appropriately and in a way that deters and prevents further assaults,� said Senator Bob Menendez, the top Democrat on the Senate Foreign Relations Committee.

�But it is hard to justify the administration�s actions thus far since they insist on stonewalling Congress from receiving any specifics about what these increased threats actually are and our strategy to confront them.�

The White House did not immediately respond to a request for comment.

A few congressional committees - including the Senate and House intelligence and the Senate Armed Services panel - said they had arranged briefings for staff or members later this week or had already had one, committee aides said.
