President Donald Trump announced on Wednesday that his son-in-law, Jared Kushner, was making "prison reform" his number one priority on the same day that the president complained that his former campaign chairman, Paul Manafort is enduring harsh prison conditions.

In a series of tweets on Wednesday, Trump argued that he should have been told by the U.S. government that Manafort was being investigated for tax and bank fraud before he hired him to run the 2016 Trump campaign.

Trump went on to complain that Manafort is "now serving solitary confinement - although convicted of nothing."

At a meeting with black pastors on Wednesday, Trump told reporters that Kushner's "number one" goal had become "prison reform."

"Who would have thought? Who would have thought?” the president reportedly said.
