Vice President Kamala Harris quickly became the presumptive Democratic nominee for president last month, but her rapid and coordinated ascendance has raised questions about what she knew about President Biden's cognitive state.

American voters in Houston and New York City spoke with Fox News Digital about their thoughts on Harris, whether she knew about Biden's cognitive condition and if they think Biden is up to the job with five months left in his presidency.

Biden stepped aside from seeking re-election last month under intense party pressure following a brutal debate performance in June that raised concerns over whether he could beat former President Trump.

Mari from New York City told Fox News Digital that Harris likely passed Biden "in the hall and could tell if he was a little off or not," but shrugged that it was acceptable to be "confidential and discreet about someone's health" even if they are the president.

"I'm pretty sure she probably knew something," Shakira from Houston said of Harris, adding, "I feel like he can finish the race pretty strong, I feel like he's done a pretty good job."
