Biden slams 'loser' Trump for using the language of 'Nazi Germany' after ex-president compared his opponents to 'vermin' and said migrants are 'poisoning the blood of our country' - at San Fran fundraiser on eve of APEC 2024

President Joe Biden repeatedly went after Donald Trump at a fundraiser in San Francisco on Tuesday night on the eve of a massive world leader summit, declaring his Republican rival 'shouldn't be president.'

'There's a lot of reasons to be against Donald Trump but d*** he shouldn't be president,' Biden said.

He criticized Trump for comparing his political rivals to 'vermin,' saying it was comparable to what was heard in Nazi Germany, and bragged about Democratic victories in last week's state elections, calling Trump a loser.

Several polls have shown Trump leading Biden in a head-to-head match up in the 2024 president election. Biden bashed Trump by name multiple times before the crowd of 2,500 wealthy donors at the so-called 'super event.' They repeatedly cheered the president on.

Biden also compared Trump's comments comparing his political rivals to 'vermin' to rhetoric one would hear in Nazi Germany.

'And in just the last few days, Trump has said it returns office he's gonna go after all those who oppose him and wipe out what he called the vermin in America, quote the vermin in America - a specific phrase because it's just a specific meaning,' Biden said.

'It that goes language you heard Nazi Germany in the 30s. That is even the first time. Trump also recently talked about blood of America has been poisoned. The blood in America has been poisoned. Again, echoes the same phrases used in Nazi Germany.'

Trump, in a rally in New Hampshire over the weekend, said, if re-elected, 'we will root out the communists, Marxists, fascists and the radical left thugs that live like vermin within the confines of our country that lie and steal and cheat on elections.'

Biden and Vice President Kamala Harris spoke at the reception, hosted by California Gov. Gavin Newsom. It was expected to bring more than $3 million for the president's reelection campaign, Politico reported, and is being billed a 'super event' for the Biden campaign.

In his short remarks, Biden didn't hold back. 

He called out Trump for his verbal attacks on Nancy and Paul Pelosi. Paul Pelosi has been in court this week as the trial of the man who attacked him with a hammer. 

The crowd booed as Biden talked about the former speaker, who lives in San Francisco and represents the city in Congress. 

'On more than one occasion in recent weeks, he's made a joke about the assaults on Nancy Pelosi's husband,' Biden said of Trump. 'There's no place in America for political violence.'

Biden also cited Tuesday's election results - including winning the abortion fight in Ohio, Gov. Beshear's victory in Kentucky, and Democrats' legislative wins in Virginia.

'But since I came off the sidelines to go toe to toe with Donald Trump, we haven't stopped winning and he hasn't stopped losing,' he aid.

'You remember Trump told us he was going to win so much we'd get get tired of winning,' he said, adding:  'Oh man, I shouldn't get started.'

'Let me tell you one thing that's true. We got tired of Trump. The truth is the guy can't get tired of losing,' Biden said as the crowd roared in applause.

President Biden is in San Francisco for a four-day trip. His meeting with China's President Xi Jinping is the main event in the city, where leaders from the 21 economies that make up the Asia-Pacific Economic Cooperation forum are gathering for their annual summit.

Biden and Xi will sit down Wednesday at Filoli, a secluded estate along Northern California's coastal range.

U.S.-China relations have been frayed for months, but the White House hopes a chugging U.S. economy and slowing unemployment can bring it new credibility in Biden's talks with other leaders.

'The president really feels we've got the wind at our back here,' said White House national security spokesman John Kirby on the flight west.

Additionally, Biden has been urged to meet San Francisco's homeless and see the city's squalor first-hand while he's in the city by the Bay. Social rights advocates have criticized the recent cleanup spree of San Francisco streets, saying it's merely not to embarrass the country when all the foreign leaders are in town.

But while Asian-Pacific issues are on the table, Biden will also work to keep the Israel-Hamas war from exploding into a broader conflict and to persuade Republican lawmakers to continue to spend billions more on the costly Ukrainian effort to repel Russia's nearly 21-month old invasion.

'President Biden this coming week will be doing a lot more than just meeting with President Xi,' White House national security adviser Jake Sullivan told reporters on Monday. 

He added that Biden would put forward his economic vision for the region, make the case that the U.S. is 'the very eminent driver' for sustainable economic growth in the Asia-Pacific, and hold the region out as critical to U.S. economic growth. 

While in San Francisco, Biden also will attend a fundraiser Tuesday night for his re-election. He'll also hold a bilateral meeting with Mexican President Andrés Manuel López Obrador.
