Some Democratic financial investors have expressed "buyer’s remorse" for rallying behind Vice President Kamala Harris as the party’s new nominee, questioning her ability to execute policy goals, according to Shark Tank investor Kevin O'Leary.

In speaking with financial investors, including some who made hefty donations to the Democratic Party, O'Leary was told, "Some of us are having buyer's remorse."

"It’d be important to leave aside the politics and ask, ‘What has Kamala Harris actually done, actually achieved?" O'Leary said Tuesday evening during an interview with Fox News anchor Jesse Watters. "If I was hiring her, and I’m not trying to be partisan, I’d ask her, ‘What was the goal? What did you achieve?'"

When asked what he thought Harris would say as her biggest accomplishment, the mega-millionaire investor responded, "I don’t know because I don’t know of one."

O’Leary’s remarks come amid growing scrutiny, since Harris emerged last week as the de facto Democratic nominee, over her perceived lack of achievements as vice president and mismanagement of the illegal immigration crisis at the southern border.

"I can tell you this: in the next two weeks, the happy talk is gonna have to stop because someone’s got to sit her down and say, ‘Let’s talk inflation, let’s talk border, let’s talk policy on energy, let’s talk policy on foreign affairs,'" O'Leary said.

Even Harris supporters who attended her address last week at the American Federation of Teachers Convention had difficulty naming just one of her policy accomplishments, Fox News reported Wednesday.

"I'm not sure I know enough about her accomplishments to answer that question," Eric, a Harris supporter from Massachusetts, told Fox News.

O’Leary warned that electing someone who lacks executional skills could lead the United States down a similar path as Canada.

"I ask everybody to look north to Canada. When a young Justin Trudeau swept in, nobody cared about his executional skills or what he’d ever done or anything," O’Leary said. "They just thought he was the 'it' guy. Look at the country now: it’s wiped out. It turns out the guy had no executional skills."

"[Harris’s] gotta have some ideas of how to run the country," O’Leary added. "You might hate Trump, but he has this track record of policy."
