Paul Manafort, President Trump’s former campaign chairman, has been hospitalized for a cardiac event, according to a new report.

Manafort is serving a seven-year sentence for charges related to special counsel Robert Mueller’s investigation in a federal prison in Pennsylvania.

“Manafort has been recovering since last Thursday at a local Pennsylvania hospital under the watch of correctional officers. Sources tell ABC News the 70-year-old longtime Republican strategist is stable and could be released soon,” ABC News reported.
