Joe Biden pushed back against a challenge from President Trump to take a cognitive test during an interview that will air Thursday, reports Yahoo News.

Why it matters: The Trump campaign has been attempting to revamp its attacks against the former vice president, arguing that his mental faculties are diminished.

During a recent interview with Fox News' Chris Wallace, Trump issued a challenge: "Let’s take a test right now. Let’s go down, Joe, and I will take a test. Let him take the same test that I took."

  • Biden's response: "No, I haven’t taken a test. Why the hell would I take a test? C’mon, man. That’s like saying, 'You — before you got on this program you took a test where you’re taking cocaine or not, what do you think? Huh? Are you a junkie?'" he said during an interview that'll air during the joint virtual convention of the National Association of Black Journalists and National Association of Hispanic Journalists.

The backdrop: Trump has repeatedly boasted about scoring highly on the Montreal Cognitive Assessment, which is typically used to test for dementia. The test is a series of relatively basic questions that are not meant to gauge intelligence.

  • Biden has maintained that he will allow the public to make their own determinations regarding his mental and physical fitness.

Biden's hardline Russia reset

When he talks about Russia, Joe Biden has sounded like Ronald Reagan all summer, setting up a potential Day 1 confrontation with Russian President Vladimir Putin if Biden were to win.

Why it matters: Biden has promised a forceful response against Russia for both election interference and alleged bounty payments to target American troops in Afghanistan. But being tougher than President Trump could be the easy part. The risk is overdoing it and making diplomacy impossible.

Durbin on Barrett confirmation: "We can’t stop the outcome"

Senate Minority Whip Dick Durbin (D-Ill.) said on ABC's "This Week" Sunday that Senate Democrats can “slow” the process of confirming Supreme Court nominee Amy Coney Barrett “perhaps a matter of hours, maybe days at the most," but that they "can’t stop the outcome."

Why it matters: Durbin confirmed that Democrats have "no procedural silver bullet" to stop Senate Republicans from confirming Barrett before the election, especially with only two GOP senators — Lisa Murkowski of Alaska and Susan Collins of Maine — voicing their opposition. Instead, Democrats will likely look to retaliate after the election if they win control of the Senate and White House.
