Trump says Biden 'not qualified' to be president

US President Donald Trump, speaking to a campaign rally in Henderson, Nevada on Sunday, claimed Democratic presidential candidate Joe Biden has a "mental problem" and is "not qualified" to be president.

"I deal with all of these people and they don't have the kind of mental problem that Sleepy Joe has. They're very sharp. Kim Jong un, Kim Jong un doesn't know about the problems that Joe has. We need very sharp people."

Trump also said vice presidential nominee Kamala Harris is "the worst."

He added, "You know, we're going to have a woman president someday, not going to be her."

Trump claimed credit for his handling of the coronavirus, saying he was ahead of others in his decisions to shut down the economy.

Trump said that at the time Biden accused him of being xenophobic, but now that now Biden has changed his mind and says Trump didn't act soon enough.

The rally came the night before Trump was to travel to California to receive a briefing on the devastating wildfires racing through the region.

He has largely been silent on the blazes that have claimed dozens of lives in Oregon and California.
