Rep. Tom Kean Jr. (R-NJ) said Tuesday that depression, not a mystery illness, was behind his nearly four-month disappearance from Congress.
Kean had not cast a vote since March 5. He missed more than 100 votes.

His office had previously blamed only a vague "personal medical issue."
"Several months ago, due to health concerns, I entered the hospital for some testing," Kean told the House. "I did not believe that this would result in a long-term stay. I was given the diagnosis of depression."
"They explained to me that this would be the fastest way to recovery," he continued. "And to be honest, I was hesitant. I didn't think that I had time for it."
Kean admitted that he had "responsibilities to my constituents" and "responsibilities to this institution."
"But depression is so much more than that," Kean said. "It is physical. It is emotional. And until you experience it yourself, it is difficult to fully understand how powerful this illness can be."
Kean, a second-term lawmaker, is still running for reelection. President Donald Trump has endorsed him. He'll face Democrat Rebecca Bennett, a former Navy helicopter pilot, in November.
"Because today, I stand before you healthier, stronger, and excited to return to the work that I love," Kean noted.
"This is not a partisan issue," he said. "It touches every community, every family, and every corner of this country."
