U.S. president Trump asks for resignation of Attorney General Jeff Session after the 2018 Congressional elections. The Democratic Party gained a majority in the House of Representatives, with the Republican Party retaining control of the Senate. This makes further investigations into Russian meddling in the 2016 presidential election likely. The official probe into this meddling is being conducted by Robert Mueller, Special Counsel, which is supervised by Assistant Attorney General Rod Rosenstein because Jeff Sessions recused himself from the investigation. 

The resignation leads to the Justice Department being headed by Matthew Whitaker, Mr. Session's top aide. Mr. Whitaker, a former prosecutor, is a conservative legal advocate who was critical of the Mueller investigation, in several tweets cited in this WSJ report, calling it  political fishing expedition," and calling for cutting the budget of the Mueller investigation to make it ineffective. Mr. Whitaker now supervises the Mueller investigation for 210 days till a successor is nominated by Mr. Trump.
