Washington (CNN) Michael Flynn's sentencing is delayed again.

The sentencing hearing for President Donald Trump's first national security adviser is now set for February 27, more than two years after he pleaded guilty to lying to the FBI. The delay comes days after Flynn asked the court to allow him to withdraw his guilty plea , because he now claims he is innocent.

Flynn had been set to be sentenced in two weeks for lying to the FBI in the early days of the Trump administration, and prosecutors had sought jail time for him. He faces a likely sentence of zero to six months in prison.

It's unusual for a relatively straightforward single charge like Flynn's to hang in the court system this long -- but Flynn's case has been unusual for the political attention it's drawn.
