Kamala Harris planned on Saturday to release a report on her health and medical history that would conclude that “she has the physical and mental resilience necessary to successfully discharge the duties of the presidency” if voters reject her November vote, according to a senior campaign adviser.

The adviser said the vice president’s aides saw the release of the health report and medical history as an opportunity to draw attention to questions about the physical fitness and mental capacity of Republican White House nominee Donald Trump. Trump, 78, also has not provided any information about his health, although he would be the oldest president-elect if Americans give him a second term in the Oval Office.

As the Guardian US reported in early October, Trump is becoming increasingly incoherent at campaign events. Medical experts said he was slurring his words, stumbling over his words, hurling profanities – and showing signs of cognitive decline consistent with someone in his 80s.

In his recent speeches, he has railed on topics ranging from his supposedly “beautiful” body to “a million Rambos” in Afghanistan. Meanwhile, Harris campaign aides pointed out that Trump backed out of an interview with CBS’ “60 Minutes” that the vice president had granted and that he refused to speak to her again after the Sept. 10 encounter debate. They argue that the former president “evades public scrutiny” and gives voters “the impression that he has something to hide and may not be fit for the job.”

“Compare her age and vitality to his,” the senior adviser to Harris, 59, said early Saturday.

The question of whether he was too weakened forced Joe Biden to abandon his bid for re-election as president in the summer. The 81-year-old Democrat dropped out of a rematch with Trump on July 21 and endorsed Harris as his successor.

Recent national polling averages show Harris with a nearly four-point lead over Trump in the Nov. 5 presidential race. But key swing states remain too close to call, and most experts expect a competitive election.

The Republican Party chose Trump as its candidate even though he was convicted in May of criminally falsifying business records to cover up hush money payments to an adult film actor who alleged an extramarital sexual encounter with him about a decade before his successful presidential run in 2016. Among others In legal trouble, he is battling criminal allegations that he attempted to illegally overturn his defeat against Biden in the 2020 election.

Trump, for his part, has claimed that Biden is “mentally impaired.” He also said that Harris was “born this way” while he had difficulty pronouncing the vice president’s name.

At a town hall in Las Vegas on Thursday, Harris told a group of undecided voters: “Using derogatory language … is not healthy for our nation.”

“I don’t admire that,” Harris said. “And in fact, I’m pretty critical of the statement of someone who wants to be president of the United States.”
