Republican Senator, Marco Rubio, has said it's in US President Donald Trump's best interest to let special counsel Robert Mueller complete his investigation.

Sen. Marco Rubio said to Fox News Sunday: "Best thing that can happen" for  US President Donald Trump and the country is for the investigation to "run the course and for all the truth to come out."

Rubio, appearing on "Fox News Sunday," echoed a number of his Republican colleagues in defending the special counsel in the face of US President Donald Trump's call last week for Attorney General Jeff Sessions to end the Mueller investigation.

Sen. Marco Rubio added that he believes any strong evidence that the president's campaign directly colluded with Russia would have leaked by now.

 

The New York Times reported that Mueller is reportedly looking at Trump's use of Twitter as part of an investigation into whether the president obstructed justice.

Meanwhile, a group of Republican lawmakers introduced articles of impeachment to remove deputy U.S. Attorney General, Rod Rosenstein, escalating a fight over Special Counsel Robert Mueller’s investigation of alleged Russian meddling in the 2016 U.S. presidential election.

A special counsel, Robert Mueller,  is investigating possible collusion between Russia and members of Trump’s campaign team. Three campaign aides have pleaded guilty to lying to the FBI and Trump’s former campaign chief, Paul Manafort, is in jail awaiting trial on charges of financial crimes.
