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.

Governments around the world are preparing to work with President-elect Biden — but they still have to navigate what could be a bumpy final 10 weeks of President Trump.

Split screen: Around the time Biden was holding his first call as president-elect with a foreign leader, Canadian Prime Minister Justin Trudeau, Trump was firing his secretary of defense, Mark Esper.

Federal judge blocks Biden's vaccine mandate for federal workers

A federal judge in Texas blocked the Biden administration from enforcing its coronavirus vaccine mandate for federal workers on Friday, citing the outcome of last week's Supreme Court ruling that nullified the administration's vaccine-or-test requirement for large employers.

Why it matters: It's a blow to President Biden's efforts to increase the U.S.' vaccination rates, though much of the federal workforce has already been vaccinated against the virus.
