Reince Priebus interviewed by Robert Mueller's team

Reince Priebus, the former White House chief of staff, has been interviewed by the federal investigator probing Russian meddling in the presidential election.

"Mr Priebus was voluntarily interviewed by special counsel Mueller's team today", said his lawyer, William Burck. "He was happy to answer all of their questions", the attorney said.

A source familiar with the matter said they expect Mueller's team to wrap up interviewing the first group of White House officials by the end of the month.

Mr Trump is under suspicion of trying to obstruct justice by removing James Comey as head of the Federal Bureau of Investigation as he investigated the Russian angle.

They're also investigating the short-lived tenure of former national security adviser Michael Flynn, who was forced to resign in February, and the drafting of a public statement about a June 2016 meeting between Donald Trump Jr. and a Russian lawyer at Trump Tower in NY.

He was also on the White House staff as the president was advising his son, Donald Trump Jr., on his statement about his June 2016 meeting with a Russian lawyer, which Trump Jr. thought would yield damaging information about Hillary Clinton. He was replaced by John F. Kelly.

Mueller's team, which consists of almost 20 federal investigators, began its interview of White House officials last month.

Mueller has requested a large batch of documents from the White House.

The interview, which took place at the special counsel's office in Washington, is a sign that Mueller's investigation is now reaching into the highest levels of Trump's aides and former aides.
