WASHINGTON (AP) — Paul Manafort, Donald Trump’s onetime presidential campaign chairman who was convicted as part of the special counsel’s Russia investigation, has been released from federal prison to serve the rest of his sentence in home confinement due to concerns about the coronavirus, his lawyer said Wednesday.

Manafort, 71, was released Wednesday morning from FCI Loretto, a low-security prison in Pennsylvania, according to his attorney Todd Blanche. Manafort had been serving more than seven years in prison following his conviction.

His lawyers had asked the Bureau of Prisons to release him to home confinement, arguing that he was at high risk for coronavirus because of his age and preexisting medical conditions. Manafort was hospitalized in December after suffering from a heart-related condition, two people familiar with the matter told The Associated Press at the time. They were not authorized to discuss the matter publicly and spoke to the AP on condition of anonymity.

Manafort was among the first people to be charged in special counsel Robert Mueller’s Russia investigation, which examined possible coordination between the Trump campaign and Russia in the 2016 election campaign.

Manafort, who was prosecuted in two federal courts, was convicted by a jury in federal court in Virginia in 2018 and later pleaded guilty in Washington. He was sentenced last March and was immediately hit with state charges in New York that could put him outside the president’s power to pardon. New York prosecutors have accused him of giving false information on a mortgage loan application.

Manafort’s release comes as prison advocates and congressional leaders have been pressing the Justice Department for weeks to release at-risk inmates ahead of a potential outbreak. They argue that the public health guidance to stay 6 feet (1.8 meters) away from other people is nearly impossible behind bars.

Attorney General William Barr ordered the Bureau of Prisons in March and April to increase the use of home confinement and expedite the release of eligible high-risk inmates, beginning at three prisons identified as coronavirus hot spots. There are no confirmed coronavirus cases at FCI Loretto.

As of Tuesday, 2,818 federal inmates and 262 BOP staff members had positive test results for COVID-19 at federal prisons across the country. Fifty inmates had died.

The bureau has given contradictory and confusing guidance how it is deciding who is released to home confinement in an effort to combat the virus, changing requirements, setting up inmates for release and backing off and refusing to explain how it decides who gets out and when.

An agency spokeswoman said more than 2,400 inmates have been moved to home confinement since March 26, when Barr first issued a home confinement memo, and more than 1,200 others have been approved and are in the pipeline to be released.

Manafort’s release was first reported by ABC News.
