Rep. Tom Kean, R-N.J., made his return to the Capitol on Tuesday, saying he was treated for depression during a nearly four-month disappearance from the public eye. It was Kean's first time in the House of Representatives since March 5, having missed more than 140 votes in the chamber since then. "Several months ago due to health concerns I entered the hospital for some testing. I did not believe that this would result in a long-term stay. I was given the diagnosis of depression," Kean said in a speech on the House floor. He said his doctors "recommended that I remain in the hospital to address my illness" and added that depression means more than "feeling sad" " "it is physical, it is emotional, and until you experience it yourself, it is difficult to fully understand how powerful this illness can be."
