1. Tax returns
Treasury Secretary Steven Mnuchin is blocking Congress’s request for Trump’s tax returns, a demand based on a 1924 anti-corruption law. On Friday, House Ways and Means Committee Chairman Richard E. Neal (D-Mass.) subpoenaed Mnuchin and Charles Rettig, the commissioner of the Internal Revenue Service. Democrats say they are ready to take the matter to court if need be.
2. The Mueller report
The White House asserted executive privilege over the full report issued by special counsel Robert S. Mueller III on Wednesday after Democrats tried to subpoena the underlying evidence in their probe of whether Trump obstructed justice. Democrats are preparing to hold Attorney General William P. Barr in contempt of Congress for refusing to honor their subpoena.
3. McGahn testimony
The White House has told former White House counsel Donald McGahn to ignore a House Judiciary Committee subpoena for documents pertaining to the Mueller investigation. McGahn was a central witness in several of 10 instances of potential obstruction identified by Mueller. He also could face being held in contempt of Congress if he refuses to appear to testify later this month.
