President Trump endorsed Rep. Tom Kean Jr. (R-N.J.) on Monday, calling him a "Great Representative" despite the congressman's absence from Capitol Hill and the campaign trail for several months.

The endorsement comes ahead of Tuesday's Republican primary in New Jersey's 7th Congressional District, where Kean is running unopposed. Trump made the announcement on his Truth Social platform, stating that Kean "will never let you down."

Kean Jr., son of former New Jersey Governor Tom Kean Sr., has not been seen publicly for months, raising questions about his whereabouts and ability to fulfill his congressional duties. The congressman has been notably absent from both legislative activities in Washington and typical campaign events in his district.

Despite his prolonged absence, Kean is expected to win Tuesday's uncontested primary election. The lack of opposition in the Republican primary means voters will have no alternative candidate to choose from.

Neither Kean's office nor his campaign have provided public explanations for his extended absence from public duties and campaign activities. The situation has drawn attention to questions about accountability and representation in the district.
