Joe Biden and the former commander in chief’s allies are threatening to reveal the shocking depths of Kamala Harris’ political incompetence if the Democrat’s ex-veep dishes any more details about her old boss’ mental decline during his term in the Oval Office,

A state that Republicans have lost only once in more than 40 years has shifted to a "toss up" in an election forecast.

Sky News contributor Kristin Tate says US Vice President Kamala Harris can use President Joe Biden’s “basement strategy” and let the media do “all the work for her”.

The first lady’s threats echo a favoured strategy of her husband, who has aggressively used litigation to go after critics.

Hunter Biden claimed in an interview that sex offender Jeffrey Epstein introduced the first lady to her now-husband, Donald Trump, which the Trumps say is false.
