Representative Thomas Kean Jr., who has been missing from Washington for nearly four months with little explanation, is back home in New Jersey.
He could be seen from the street on Wednesday evening, standing in a brightly lit front room of his Westfield home just before 8:45 p.m.
“It’s good to see you,” he said after a reporter for The New York Times rang his doorbell. He was wearing a dark suit and a red tie. “I’ll talk to you next week,” he said. “Thank you.”
Mr. Kean’s wife, Rhonda, stood in the background, smiling pleasantly. He declined additional comment and closed the door.
Aides had said that Mr. Kean, 57, was being treated for a health condition, but had offered no additional details as their boss missed more than 100 votes in the House since March 5.
Mr. Kean, a second-term Republican, is running for re-election in one of the country’s most competitive midterm races in November. He has been absent from the campaign trail, though, leaving even some of his biggest boosters frustrated.

A spokesman for Mr. Kean, Harrison Neely, said last week that the congressman was expected to return to Washington on June 30. He declined to say how long Mr. Kean had been home or to offer any additional details about the congressman’s long absence.
“He will be fully transparent on the 30th,” Mr. Neely wrote in a text message.
