Former president Bill Clinton said Kamala Harris is "extremely vulnerable" while campaigning for the Democratic presidential nominee in the final days before the election.

"She’s extremely vulnerable, more vulnerable than she deserves to be," Clinton said of Harris as he stumped for her during a Wednesday event in Phoenix, Arizona.

"There is a sliver [of voters] there that has to make up their minds, [...] and what they think of her largely depends on what they think of President Biden," Clinton added.

The comment follows another blunder by Clinton at a campaign event last week. While stumping for Harris in Georgia, he said the murder of 22-year-old nursing student Laken Riley in February—allegedly by an illegal immigrant from Venezuela—"probably wouldn’t have happened" had the suspect been "properly vetted."

"You had a case in Georgia not very long ago, didn’t you? They made an ad about it, about a young woman who had been killed by an immigrant," Clinton said at the Oct. 14 rally. "If they had all been properly vetted, that probably wouldn't have happened."

Republican nominee Donald Trump is leading Harris nationwide 47 percent to 45 percent in the razor-thin race for the White House, according to the Wall Street Journal’s latest poll released Wednesday.
