WASHINGTON - The US Justice Department on Wednesday named former FBI Director Robert Mueller as special counsel to investigate alleged Russian interference in the 2016 US election and possible collusion between President Donald Trump's campaign and Moscow.
The move followed a week in which the White House was thrown into an uproar amid rising demands by Democrats and some ofTrump's fellow Republicans for an independent probe of whether Russia tried to sway the outcome of November's presidential election in favor of Trump and against Democrat Hillary Clinton.
In a statement after the Justice Department announcement,Trump said he looked forward to a quick resolution of the matter.
"As I have stated many times, a thorough investigation will confirm what we already know - there was no collusion between my campaign and any foreign entity," he said.
Mueller, in a statement tweeted by CBS News said: “I acceptthis responsibility and will discharge it to the best of myability.”
Trump has long bristled at the notion that Russia played any role in his November election victory, but the Russia issue has clouded his early months in office. Moscow has denied US intelligence agencies' conclusion it meddled in the campaign.
But pressure on the White House intensified after Trump'sfiring last week of Federal Bureau of Investigation chief James Comey, who had been leading a federal probe into the matter, and allegations that Trump had asked Comey to end the FBI investigation.
The issue spilled over onto Wall Street on Wednesday wherethe S&P 500 and the Dow had their biggest one-day declines since September as investor hopes for tax cuts and other pro-business policies faded amid the political tumult.
"My decision (to appoint a special counsel) is not the finding that crimes have been committed or that any prosecutionis warranted. I have made no such determination," Deputy Attorney General Rod Rosenstein said in a statement announcing the special counsel.
"I determined that a special counsel is necessary in order for the American people to have full confidence in the outcome," he said.
CONGRESSIONAL PROBES TO GO ON
Lawmakers on Capitol Hill welcomed the Justice Department action, but House and Senate Republican leaders said they would go on with their own investigations of the Russia matter.
Senate Democratic leader Chuck Schumer said Mueller was theright choice for the job.
“A special counsel is very much needed in this situation and Deputy Attorney General Rosenstein has done the right thing," Schumer said in a statement.
Republican House Judiciary Committee Chairman Bob Goodlatte said he was confident Mueller "will conduct a thorough and fair investigation."
Mueller, 72, was decorated as a Marine Corps officer during the Vietnam War. A former federal prosecutor, he is known for his tough, no-nonsense managerial style. Appointed by Republican President George W. Bush, he became FBI director one week before the Sept. 11, 2001, attacks.
In 2011, he was asked by Democratic President Barack Obama for two more years. He was replaced by Comey in 2013.
Some past independent investigations have stretched for years. For example, Kenneth Starr, who investigated former President Bill Clinton, probed allegations surrounding his pastreal estate deals but later expanded the inquiry into Clinton's relations with then-White House intern Monica Lewinsky, leading to an impeachment of Clinton by the House.
