Trump's former physician sent a letter to Biden asking him take a cognitive test - and more than a dozen Republicans signed it
- Rep. Ronny Jackson, a White House doctor under Trump, has called on Biden to take a cognitive test.
- Jackson said on Thursday he was circulating a letter among House GOP colleagues.
- More than a dozen Republicans have signed the letter, which Jackson said he sent to Biden directly.
Rep. Ronny Jackson of Texas, who previously served as the White House physician under both Donald Trump and Barack Obama, is calling on President Joe Biden to take a cognitive test to prove he's fit to run the country.
Jackson told Fox News' Sean Hannity on Thursday that he was circulating a letter among House GOP colleagues because he believed Biden was "not physically or cognitively fit to be our president right now."
More than a dozen Republicans signed the letter, including Reps. Brian Babin, Pat Fallon, Bob Gibbs, and Jeff Duncan.
"We can't sit on this any longer," Jackson told Hannity on Thursday, according to Fox News. "We need to know that we can trust our president, and we need to know that he's in charge of what's going on and someone else isn't pulling the strings behind the scenes. Because that's what it looks like now."

Jackson also criticized Biden's performance overseas with world leaders at the G7 summit this week, calling it "embarrassing."
The Texas congressman later took to Twitter to say he sent the letter to Biden; the current White House physician, Kevin O'Connor; and Dr. Anthony Fauci, who is Biden's chief medical advisor.
Biden, 78, made history this year by becoming the nation's oldest president.
White House officials said last month the president was scheduled to take an annual physical exam "later this year" and would make the results publicly available, according to The Hill.
Jackson joined the White House medical team during the George W. Bush administration. He was promoted to be the top White House physician during the Obama administration and served in that role from 2012 to 2018.
Jackson later made headlines for an interview in which he said he would mix cauliflower into Trump's mashed potatoes in a sneaky attempt to get him to eat more vegetables.
In March, a report by the Pentagon's inspector general concluded that Jackson while serving in the White House made sexual remarks about a female junior employee, verbally abused subordinates, and drank on the job.
Jackson, who now represents Texas' 13th Congressional District in Congress, was one of 14 House Republicans who voted against legislation this week to establish Juneteenth as a federal holiday commemorating the end of slavery in the US. Biden signed the legislation into law on Thursday.
