Presumptive GOP presidential candidate Donald Trump's former spokeswoman, Liz Harrington, predicted that the Democrats will swap President Joe Biden out as the Democratic nominee following his debate performance.

"We're not running against Joe Biden," Harrington said on the "Furthermore with Amanda Head" podcast. "This is part of the whole show.....like, we're beating Joe Biden? No. They're putting someone else in, and they're going to continue to lie about President Trump."

Trump and Biden squared off in the first presidential debate hosted by CNN earlier this week and Biden's performance was considered very weak. 

As a result, some Democratic leaders have been scrambling to find a potential replacement for Biden, according to Politico. The White House has maintained that Biden will remain in the race.

"They're just setting up the next con, and we cannot fall for it," Harrington said. 

She went on to predict that top Democrats such as former House Speaker Nancy Pelosi, D-Calif., will likely try to talk him into stepping down. 

Harrington also praised Trump for being genuine on the debate stage the other night. 

"I know Americans hate being lied to," she said. "That's why we love Trump. Trump is the only one who doesn't lie to us, and we're just so sick of it."
