Newsom declared Biden won on 'substance,' slams Trump for 'no accountability'

California Gov. Gavin Newsom

California Gov. Gavin Newsom spoke with MSNBC in the spin room after the CNN Presidential Debate on Thursday, urging the Democrats to back President Biden despite what many have called an unconvincing performance.

"We got to have the back of this president," Newsom insisted. "You don't turn your back because of one performance. What kind of party does that?"

Newsom touted Biden's performance, claiming he had won the debate "on the substance" while blasting Trump for taking "no accountability" for his "lies."

"Talking down the American economy. Talking down, our democracy. That was alarming," Newsom said. "This is a world we're living in now."

Newsom called criticism of Biden's performance and calls to replace him "unhelpful" and "unnecessary" as he discussed Biden's work on jobs and the economy, stressing that "President's deliver" and that the party now needs to "deliver for him at this moment."

"We need to raise money, and we need to understand what's at stake. If we don't, we need to understand what's at stake," Newsom said. "If we turn our back at this critical time, there's too much."
