Representative Thomas Kean Jr. returned to Congress Tuesday after disappearing from public view for nearly four months. The New Jersey Republican said his absence stemmed from depression, though he offered few specifics to reporters waiting at the Capitol. His staff promised full transparency in an upcoming floor speech.

Kean's absence has complicated Republican efforts to defend a competitive swing seat in the upcoming midterms. House Speaker Mike Johnson acknowledged encouraging Kean to disclose more details, suggesting the condition affects many Americans and could generate public sympathy. Party leaders have struggled to explain Kean's whereabouts to concerned colleagues.

The two-term congressman missed hundreds of votes since March, raising questions about his ability to serve effectively. His Democratic opponent Rebecca Bennett has remained largely silent, while House Democratic campaign chief Suzan Delbene demanded greater transparency about his extended leave.

Kean's return comes after winning an uncontested primary in June, though some GOP operatives privately questioned whether he'd appear on the November ballot. His silence has frustrated both parties, with Democrats seeing opportunity in the seat and Republicans fearing electoral consequences.
