For three months, Tom Kean Jr., Republican representative from New Jersey, has been absent from the Capitol due to a delicate health problem of which he refuses to offer details.

Despite having missed 104 roll call votes, the 57-year-old politician has the support of President Donald Trump to seek a hypothetical reelection ahead of the primaries in his home state.

Since March 5, Kean Jr. has not voted in the House of Representatives and the staff in charge of his office has only responded to the press that his absence is due to a medical problem.

"Congressman Kean fully understands the need for transparency regarding his health. He plans to reveal all relevant information, but for now he is following his doctors' instructions and focused on his recovery," his spokesperson said in a statement to ABC News.

Good news for the absent Republican is that he has no rival in his party's primaries and also has the nation's president on his side.

“GO OUT AND VOTE FOR TOM, HE WILL NEVER DISAPPOINT YOU!” Trump wrote on the Truh Social platform.

Another point in favor of the New Jersey congressman is that he is the son of Thomas Kean Sr., former governor of that entity between 1982 and 1990.

The controversial thing about the matter is that not even Mike Johnson himself, president of the House of Representatives, knows what is happening to the congressman in question.

"I don't even know the details. I have to respect the personal privacy of a member of Congress when it comes to the issues he is dealing with, but we hope to have him back soon. We have missed him. He is a great member of Congress," he said a couple of weeks ago.

Despite his absences, Tom Kean Jr. is still far from equaling the mark of Mikie Sherrill, governor of New Jersey, who stopped showing up for 145 votes to be fully focused on winning the state election, which he achieved by obtaining 54% support among citizens.
