Following the appointment of former FBI Director Robert Mueller as special counsel to oversee the investigation between President Donald Trump's campaign and Russian officials, Sen. Lamar Alexander said the probe should continue promptly. 

The U.S senator from Tennessee said in a prepared statement:

During his service as FBI director for both President Bush and President Obama, Robert Mueller earned a reputation for independence and integrity, which are exactly the qualities needed to pursue the Russia investigation to its conclusion. The bipartisan U.S. Senate Select Committee on Intelligence should also continue its investigation, and that should include a public hearing with former FBI Director James Comey sooner rather than later.

Deputy Attorney General Rod Rosenstein made the decision to appoint a special counsel after several developments, including Trump's firing of Comey and reports that Trump asked Comey to drop the investigation into former national security adviser Michael Flynn. 

Rosenstein is slated to brief all senators on the issue today at 2:30 p.m.

Sen. Bob Corker tweeted about today's meeting.
