Mark Cuban Confronts Donald Trump Allies With Flurry of Posts

Billionaire and Shark Tank star Mark Cuban confronted Bill Ackman and Charlie Kirk, allies of former President Donald Trump 's, on Sunday with a series of posts on social media.

Trump, the GOP presidential nominee, is set to face off against Vice President Kamala Harris , who became the Democratic nominee after President Joe Biden dropped out of the race on July 21 , in November.

In a lengthy Sunday post on X, formerly Twitter , Ackman, also a billionaire, criticized Biden for dropping out of the race and the subsequent Democratic nomination of Harris as he wrote that the "American people were misled."

"How can anyone trust anything she says? Even if you carefully watch her speak or read the transcripts of the four interviews and one debate she has done, it is nearly impossible to understand what she is saying. She has yet to answer a direct question about the economy, the border, or foreign policy," Ackman, who endorsed Trump in July, wrote.

Harris has previously laid out her economic agenda as she called for higher taxes on upper-income households, bigger tax deductions for startup businesses, and greater financial assistance for first-time homebuyers.

In regard tothe southern border, Harris said during her speech at the Democratic National Convention in August, she'd revive the bipartisan border security agreement , voted down by Senate Republicans in May. With foreign policy, Harris has promised to "strengthen, not abdicate" America's global leadership, and has twice stated that the U.S. will defeat China in the "competition for the 21st century."

In response to Ackman's post, Cuban, a frequent critic of Trump , wrote: "When the competition hires a new CEO and she is kicking your a**."

Ackman, the Pershing Square Capital Management CEO, previously voted for Biden, writing in his X post, "I voted for because after first term, I believed the country would benefit by a more centrist candidate."

He also apologized "for casting my vote for Biden," adding that "it was a big mistake."

In another X post seemingly responding to Ackman's claim that "Harris's entire candidacy relies on support from an undisclosed cabal of party leaders," Cuban asked, "Would you consider fund raising a good indication of relative support? She only raised 3x the amount he did."

By late August, just four weeks into her campaign, Harris had taken in around $500 million, according to a report from Reuters that cites four anonymous sources "familiar with the fundraising effort."

Of the reported $500 million, $200 million was raised during the first week of Harris' campaign, with a total of $310 million raised in July. In comparison, the campaign of Trump reported raising a total of $138.7 million during July.
