Former White House national security adviser Michael Flynn was charged Friday with making false statements to federal investigators about his conversations last December with Russia's ambassador to the US at the time, Sergey Kislyak.

Flynn is the latest to be charged in special counsel Robert Mueller's ongoing investigation into whether President Donald Trump's campaign coordinated with Russia to swing the 2016 election.

The Justice Department appointed Mueller as special counsel in May after Trump abruptly fired then-FBI Director James Comey, who had been looking into the president and his potential connections with Russians.

Since taking over the investigation, Mueller's team has charged four people once affiliated with the Trump campaign or administration. Only one of those charged has so far pleaded guilty.
