Michael Flynn's cooperation with the government has ended -- and prosecutors want him sentenced quickly

Michael Flynn's cooperation with the government has ended, according to his lawyers and federal prosecutors.

The retired U.S. Army general and President Donald Trump's former national security adviser had agreed to provide testimony in special counsel Robert Mueller's probe after pleading guilty to lying to FBI agents.

He is no longer providing testimony as part of any federal investigation, and prosecutors hope to set a sentencing date as soon as possible.

Flynn's lawyers, however, have asked a court for more time to examine evidence against him and have repeated a request for security clearance to review sensitive evidence.
