Jackson has been on a medical leave of absence since June. He's being treated at Mayo for bipolar disorder.
On Monday, Congressmen Bobby Rush and Danny Davis visited with Jackson and said he was headed back to the clinic for more treatment.
"He looked good," said Davis. "He had some light moments, then he had some serious moments. He smiled at some moments. Other moments were not so pleasant."
"Jesse displayed sharpness, truthfulness of his mental state," said Rush.
On Saturday, he made his first public comments to his constituents via a recorded message, asking for patience. "I am anxious to return to work on your behalf but at this time it's against medical advice," he said in the call.
The phone recording came a few days after a he was spotted outside his home smoking a cigar.
Davis and Rush made call for calm and understanding.
"Once he has been helped, he will be as good as before the illness ever struck," said Davis.
It is not clear when Jackson may return to work.
Rush said they didn't discuss the new federal investigation Jackson is now facing.
