Short of eating a live infant on the Senate floor, in front of C-Span cameras, this administration can do anything it wants and Congress will not do one damn thing about it. There is zero leadership in Congress.
This is another demonstration as to how politically inept the Democrats are. As the White House pushes the envelope, lying regularly and refusing to testify (hell, claiming not to be part of the exec branch!) it makes Congress look terrible. Then liberals, rightly so, start to think that the Democrats aren't so hot either and voters become less likely to turn out.
No matter how clear the lesson shown by the GOP, the Dems won't take it: feed your base, win over and over; ignore your base and lose (or squeak by if the nation HATES your opponent).

No doubt, some will claim without 60 votes the Senate is powerless, but that's not true. They could shut down everything, issue subpoenas left and right, find officials in criminal contempt, etc.
