United States President Joe Biden does not have an "age problem" but a "competency problem," according to his predecessor Donald Trump.
Biden is "grossly incompetent" and "was dumb 25 years ago," Trump told the attendees of a summit organized by Moms for Liberty.
The leader of US Democrats is "crooked as a three-dollar bill" and "corrupt" and he and his family were paid "millions" by China and several other countries, Trump also claimed.
