Trump says Biden's problem is not age but 'competence' in post-debate rally

President Biden's performance during Thursday's presidential debate gave former President Trump a fresh spin on familiar criticism during his first post-debate appearance on Friday.

Why it matters: Biden acknowledged that his debate skills had diminished and referenced his age in a post-debate appearance of his own but not before whispers of "doom" and worry among House Democrats had already spread.

"Joe Biden's problem is not his age," Trump said during his rally in Chesapeake, Va. He later added, "it's his competence."

The former president also called the debate a "victory" for him.

Catch up quick: As critics have highlighted, Trump is not a flawless candidate. He was convicted in a New York criminal trial of 34 felony counts for falsifying business records linked to a $130,000 hush money payment.
