Fact Check: False

Trump claimed that “millions” of people are dying in Ukraine and that the deaths were being underreported, blaming the Biden-Harris administration for them. The war in Ukraine is extraordinarily bloody but no estimates suggest casualties anywhere close to “millions”. The U.S. and other western countries estimate the Russia has lost between more than 300,000-500,000 troops killed and wounded since the 2022 invasion.

Some estimates are even higher. The Economist in July estimated between 462,000 and 728,000 Russia soldiers could have been out of action by mid-June this year.

Ukrainian losses are estimated to be significantly lower but nonetheless in the tens of thousands. Ukraine’s government has claimed it has lost around 30,000 men, but Western governments and independent groups assess killed and wounded could well over 100,000. Thousands of Ukrainian civilians have also been killed. The U.N. has confirmed that more than 11,500 Ukrainian civilians have been killed since February 2022, but the U.N. and most experts believe the real number is significantly higher. Many civilians have been killed in occupied areas where reporting is prevented by Russia.

Millions of Ukrainians have been displaced by the war. The U.N. estimated 14.6 million Ukrainians were forced from their homes, with more than 6.5 million have fled the country since 2022.

“Biden doesn’t go after people, because supposedly China paid him millions of dollars,” Trump said. “He’s afraid to do it. Between him and his son. They get all this money from Ukraine. They get all this money from all of these different countries and then you wonder why is he so loyal to this one, that one, Ukraine, China? Why is he?”

Financial records made public last year show details of an intricate web of about $19.3 million in payments from foreign sources that were directed to the Biden's associates and at least three Biden family members.

But not the president. The memos show that about $14.4 million in payments were made to "associates" of the Biden family or accounts associated with those individuals. These payments went largely to Hunter Biden business partners. From 2014 to 2020, Biden family members received about $4.94 million from sources with ties to Ukraine, Romania, China and Kazakhstan. The memos show these close to 90% of these payments went to Hunter Biden or his businesses. Other money went to the president's brother and the wife of Biden's late son Beau.

The memos that detail these payments don’t provide evidence that Joe Biden took any official actions because of his family’s business dealings.

Minnesota Gov. Tim Walz said he is "feeling great" about his running mate's debate performance while calling Trump's "unhinged."

"You saw a president for all Americans," Walz told ABC News about Harris, saying she laid out plans for the country and the economy, such as to help small businesses and make home ownership easier.

"On the other side, you saw a nearly 80-year-old Donald Trump angry and unhinged," he said.

He said Trump, meanwhile, brought "nothing" except "anger" and "resentment."

"He shouldn't be anywhere near the White House," Walz said. "If it weren't so dangerous, it reminds you of an old man yelling at the clouds."

Asked by ABC News' Martha Raddatz for further clarification on where the Harris-Walz ticket stands on abortion restrictions, Walz said women need to make decisions about their health care, "not Donald Trump."

In a post on her Instagram account, Swift said she watched the debate, has done her research and made her choice on who to support in 2024 race.

"I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election," Swift wrote.
