"Yeah, politicians have gaffes. I don't remember anybody like this having this many gaffes, this often," the Fox News host said Thursday night on "Hannity."
Biden is trying to move further to the left to placate progressive voters, Hannity claimed. The host also criticized Biden for backing the Green New Deal, the progressive plan to address climate change.
"Biden knows he's not, well, radical enough to survive the new extreme Democratic Party," Hannity said. "Last night he did sign on to the radical Green New Deal. Wasn't that nice."
During CNN's seven-hour climate change town hall Wednesday night, Biden was asked if U.S. Rep. Alexandria Ocasio-Cortez's legislation "goes too far."
"No," Biden responded, suggesting it could go further.
The Fox News host ripped Biden for his response.
"So he has to now spin it in a million different directions trying to keep his story straight. Trying to keep it together on the campaign trail," Hannity said.
Ultimately, Hannity said, Biden's "biggest opponent is himself."
