U.S. Attorney General questioned in Russia probe

U.S. Attorney General Jeff Sessions was questioned last week by the special counsel's office investigating possible collusion between Russia and President Donald Trump's 2016 campaign, the U.S. Department of Justice (DOJ) said on Tuesday.
The Department of Justice confirmed that Sessions met with special counsel Robert Mueller's office for the first time last week.
Trump on Tuesday said he was not concerned by the development, "No, I didn't, but I'm not at all concerned."
But the meeting marks the first time Mueller's team has interviewed a member of Trump's cabinet.
Sessions was a top adviser to Trump's campaign before the president nominated him to lead the DOJ. At his confirmation hearings, Sessions denied meeting with Russians during the presidential race. But when news broke that he'd in fact met several times with Russian ambassador Sergei Kislyak, the attorney general caved to pressure to distance himself from his department's investigation into possible collusion.
U.S. Attorney General Jeff Sessions said, “I have now decided to recuse myself from any existing or future investigations of any matter relating in any way to the campaigns for President of the United States."
Investigators could also be interested in Trump's decision to fire FBI Director James Comey soon after Sessions' recusal. Both these events paved the way for the DOJ to appoint Robert Mueller to lead the investigation.
Trump has vehemently denied allegations that his campaign worked with Moscow to win the election. Donald Trump had said, “There has been no collusion between the Trump campaign, and Russians, or Trump and Russians. No collusion."
Another matter for the Mueller probe is a meeting in March 2016, during the campaign. A man, George Papadopoulos said he suggested brokering a meeting between Trump and Russian President Vladimir Putin. Papadopoulos pleaded guilty to lying to investigators and is now cooperating with Mueller's investigation. Sessions first said he did not recall Papadopoulos' proposal. But, he now says he does remember it.
As Mueller's probe continues, some have wondered whether Trump himself will face questions in the matter.
