President Trump’s one-time campaign chair Paul Manafort was treated at a hospital for a “cardiac event” while serving his more than seven-year sentence behind bars, ABC News reported Tuesday, citing sources.

Manafort was convicted of lying to the feds during special counsel Robert Mueller’s investigation, and suffered the unspecified “event” last week, according to two sources familiar with the situation.

He had been serving out his sentence in a federal correctional institute in central Pennsylvania.

Manafort has been recovering since last Thursday at a local Pennsylvania hospital while under guard.

Sources tell ABC News the 70-year-old longtime GOP strategist is stable and could be released from the hospital soon.

Manafort was scheduled for a court appearance Wednesday but his attorney was informed that he would not be appearing.
