President Donald Trump unleashed a new attack on special counsel Robert Mueller’s investigation on Thursday, as he insisted his White House is operating well and met with Senate Republican leaders.

MUELLER ATTACK

Trump called Mueller’s investigation into Russian interference in the 2016 presidential election a “disgrace to our Nation,” slamming the probe in a series of tweets. Trump’s attack comes after his ousting last week of Jeff Sessions as attorney general, and the appointment of Acting Attorney General Matthew Whitaker — who publicly criticized Mueller’s inquiry before working at the Justice Department.

Trump also falsely said Mueller worked for President Barack Obama for eight years. Mueller, a Republican, was FBI director under former President George W. Bush for almost eight years and headed the bureau under Obama for four years.

SMOOTH-RUNNING WHITE HOUSE

Having removed his deputy national security adviser, Trump said “anytime I even think about making changes, the FAKE NEWS MEDIA goes crazy, always seeking to make us look as bad as possible!” (The president also is said to be close to ousting Homeland Security Secretary Kirstjen Nielsen.)

Trump said the White House is “running very smoothly and the results for our Nation are obviously very good.” Trump removed deputy national security adviser Mira Ricardel on Wednesday after a feud with first lady Melania Trump’s office.

SENATE GOP MEETING ON LAME DUCK

Following a visit with Marines who responded to a fire at their Washington barracks in September, Trump met with Senate Republican leaders including Sen. Mitch McConnell about the agenda for the lame-duck session of Congress. The meeting covered the farm bill, border security, disaster relief funding and prison reform, among other topics, said deputy press secretary Hogan Gidley.

The White House separately announced Thursday that Trump will travel to California on Saturday to meet with individuals impacted by the wildfires in the state.

The meeting with GOP senators came a little more than a week after the midterm elections, in which the GOP retained a Senate majority but lost the House to Democrats.
