Michael Flynn, the former national security advisor of US President Donald Trump pleaded guilty to making false statements to the FBI over the possible collusion between the Trump campaign and Russia during last year's US presidential elections.
Flynn appeared before a federal court to plead guilty after ex-FBI director Robert Mueller, who has been probing involvement of Trump's team member in alleged Russian interference in last year's presidential election, announced that Flynn was charged with "wilfully and knowingly" making "false, fictitious and fraudulent statements" to the FBI about his conversations with Russia's then ambassador to the US Sergey Kislyak.
Flynn, a retired Army general who was fired from his White House post in February after revelations he had misled Vice President Mike Pence about his conversations with the Russian ambassador, is a central figure in the federal investigation led by Special Counsel Robert Mueller.
The charge against him is another escalation in an investigation that has cast a cloud over the Trump administration since the Republican president took office on Jan. 20.
In a filing with the US District Court for the District of Columbia, the office said Flynn made false statements to the Federal Bureau of Investigation on Jan. 24.
