More than three dozen Republicans signed a letter calling U.S. President Joe Biden to take a cognitive test to measure if he is mentally fit for the office. The cognitive test was taken by former President Donald Trump during his presidency.

Some of the Republicans that signed the letter were Rep. Ronny Jackson, Republican leadership members House Republican Conference Chairwoman Rep. Elise Stefanik of New York, and GOP conference vice chairman Mike Johnson of Louisiana, The Daily Wire reported.

Several members of the GOP Doctors Caucus and Republican Study Committee Chairman Rep. Jim Banks of Indiana also joined the signing of the letter.

They express "concern" with Biden's current cognitive state in their letter. Biden is the oldest president to take office at 79.

Republicans said they want to ensure that Biden is fit for leadership.

Republicans' Letter to U.S. President Joe Biden

The letter said that the American public deserves full transparency on the mental capabilities of their highest elected leader, according to a Daily Mail report.

Republican lawmakers cited situations wherein the president forgot the names of senior Cabinet officials, as well as misreading clearly-marked figures.

The group went on to imply that Biden has shown symptoms of Alzheimer's Disease.

Jackson wrote in the letter that the Alzheimer's Association lists changes in mood and personality and being easily upset as among the ten signs of mental decline. He then cited that Biden displayed the type of mood change during a cabinet meeting on January 24.

Jackson was referring to an incident when Biden called a White House reporter a "stupid son of a b****" without realizing that his microphone was on. Biden since then apologized to Fox News reporter Peter Doocy after the incident.

Donald Trump Taking the Cognitive Test

The former presidential doctor wrote that it was not a partisan issue, adding that when he asked Trump to take the cognitive test, the former president was eager to do so, according to a Fox News report.

The lawmakers added in the letter that they believe that regardless of gender, age, or political party, all presidents should follow the example set by Trump to show a fit mental ability in leading.

The White House earlier reported that Trump had passed the test, reportedly scoring a 30 out of 30, per Newsweek.

Trump had taken the Montreal Cognitive Assessment, which is a 10-minute test designed to detect mild cognitive impairment such as the early signs of dementia. However, medical and public health experts noted that the cognitive test is not an indicator of I.Q.

Experts added that the president's fixation on the Montreal Cognitive Assessment is puzzling as the test is normally done if someone is concerned that they or their loved ones may be experiencing cognitive decline.

Ziad Nasreddine, the neurologist who created the test, said that it is not meant to measure I.Q. or intellectual skill in any way, according to a Washington Post report.

The former president has talked about the test publicly, telling Fox News's Sean Hannity in a phone interview that he "aced it."
