Democratic presidential candidate Joe Biden told a crowd of supporters on Tuesday that "we choose truth over facts," apparently referring to the Democratic Party.

"We choose science over fiction; we choose truth over facts," Biden said, drawing applause.

The former vice president has a history of tripping over his words.

Biden continues to hold a formidable lead in national Democratic primary polls. He leads the next two closest opponents, Sen. Bernie Sanders (I, Vt.) and Sen. Elizabeth Warren (D., Mass.), by over 15 percentage points.

Although he avoided another awkward exchange with Sen. Kamala Harris (D., Calif.) in the most recent Democratic debates, some in the media criticized his performance, with one MSNBC panel noting he seemed to "forget words." Sen. Cory Booker (D., NJ) went after the former Vice President at the debate, however, calling him out for dodging on whether he advised former President Barack Obama’s against mass deportations.

Biden, for his part, has attacked Booker’s record on policing during his tenure as mayor of Newark, pointing to the use of stop-and-frisk.
