Warren Buffett 'to do whatever it takes' to defeat Donald Trump

Buffett tears into Trump for his business record, bankruptcies; says he will escort people to polls

Billionaire investor Warren Buffett has said he'll do whatever it takes to defeat Donald Trump, including escorting people to the polls himself.

Campaigning with Hillary Clinton in Nebraska on Monday, Buffett savaged Trump's business record, questioning his bankruptcies and asking why the Republican presidential candidate won't release his tax returns.

The so-called "Omaha Oracle" then announced a new campaign called "Drive 2 Vote," designed to bring out voters in Nebraska's second congressional district, which offers a single Electoral College vote to the district winner.

"I will take at least 10 people to the polls who would otherwise have difficulty getting there," said Buffett, adding that he had reserved a 32-seat trolley for the day with a goal of getting the highest-percentage turnout of any congressional district in the country.

"Let's give America a civics lesson."

Nebraska is one of two states that assign some electoral votes based on the results within congressional districts. 

While the state is Republican overall, President Barack Obama won a vote here in 2008 in the more liberal district where Clinton appeared Monday, which includes Omaha and the suburbs.

The boundaries have since been redrawn to make the district less blue.

The Midwestern stop came amid a clash between Trump and a Muslim-American family who spoke against him at the Democratic National Convention. Trump responded by attacking Khizr and Ghazela Kahn, whose son served in the US Army and was killed in Iraq in 2004.

Buffett called Trump's comments "the final straw," arguing that his family had not sacrificed like military families.

Buffett, who endorsed Clinton last year, was the latest in a series of business leaders attacking Trump as Clinton seeks to woo moderate and independent voters.

Dallas Mavericks owner Mark Cuban campaigned with Clinton over the weekend, and former New York City Mayor Michael Bloomberg delivered a searing indictment of Trump's economic proposals during the Democratic National Convention.

Before several thousand people gathered at an Omaha high school, Buffett challenged Trump to agree to a meeting where they would both release their tax returns.

He also said that after Trump listed his casino and hotel firm on the New York Stock Exchange in 1995, investors lost money, even though "in 1995 when he offered this company, if a monkey had thrown a dart at the stock page, the monkey on average would have made 150%."

Buffett repeated long-held assertions that the tax code favors the wealthy, which Clinton echoed, pledging to pay for new programs through more taxes on the rich.
