Senate GOP aides say Lew will be called to account for the White House’s tactics when he comes before the Senate Finance Committee.

“He’s coming to the Senate from the chief of staff’s role in the White House and this White House just points the finger at everyone else. It refuses to take the blame for the bad things that are happening. This is a White House that is overly political and not really interested in alternate points of view,” said a senior Senate GOP aide.

“He’s going to be facing a lot of questions related to his involvement in the White House. He’s the top dog over there. He’s responsible for the direction,” the aide said. “It’s a shame the president would send along such a divisive figure.”
