Representative Tom Kean Jr., a New Jersey Republican, has been absent from Congress since March due to what his father described as a "serious illness," missing 88 votes during a period when the House Republican majority operates with a narrow margin.

Former New Jersey Governor Tom Kean Sr. said his son could potentially return to Congress within weeks, though he did not provide specific details about the nature of the illness that has kept the congressman away from his duties.

Kean Jr. represents a competitive swing district in New Jersey, making his extended absence particularly notable given the slim Republican majority in the House of Representatives. Every vote carries significant weight in the closely divided chamber.

The congressman's prolonged absence comes during a critical period for House Republicans, who have faced challenges in advancing their legislative agenda with their narrow majority. Missing members can complicate vote counts on key legislation and procedural matters.

Kean Jr. was first elected to Congress in 2022, flipping a Democratic-held seat in New Jersey's 7th Congressional District. His district is considered one of the more competitive seats in the state and could be closely watched in future elections.
