Reporter: Tonight, with a little over 100 days until the 2020 election, president trump sharpening his attacks on Joe Biden. If Joe Biden got in, first of all, he won't call the shots. The people, the radical left people that's around him will call. Reporter: In that Fox News interview, Chris Wallace pressing president trump on his repeated claims that his likely opponent isn't fit for office. I tell you what. Let's take a test. Let's take a test right now. Let's go down, Joe and I will take a test. Reporter: The president falsely insisting that Biden supports defunding the police. Suggesting that Democrats make America less safe. Biden wants to defund the police. No, sir, he does not. Did you read the charter that he agreed to with -- It says nothing about defunding the police. Reporter: The Biden campaign calling that a "Smear" and a "Lie." And blasting the president for his handling of the pandemic. Saying in a statement, "There is one candidate in this race who has failed to keep the American people safe this year -- Donald Trump." Mr. President, please listen to your public health experts instead of denigrating them. Do your job, Mr. President. Reporter: And with that new ABC news/"washington post" poll finding Americans trust Biden on the virus by a 20-point margin, the president, asked point-blank, will he accept the election results come November? Can you give a direct answer you will accept the election? I have to see. Look, you -- I have to see. No, I'm not going to just say yes. I'm not going to say no, and I didn't last time either. Reporter: The Biden campaign had a response for that too. Saying, "The American people will decide this election. And the United States government is perfectly capable of escorting trespassers out of the white house." In that interview, president trump conceded he won't be holding in-person campaign rallies until covid-19 is solved. Instead, holding phone-in rallies streamed on Facebook, including one just moments ago. Tom? Andrew, thank you.
