More than 50 House Republicans Wednesday are calling for President Biden to take a cognitive test, as the president's opponents, and even some allies, question his fitness for the job at age 79. Fifty-four Republicans signed the letter, addressed to President Biden, which was led by Rep. Ronny Jackson, R-Texas. That's up from 13 co-signers on a similar letter Jackson led in June 2021, and 37 co-signers on a letter in February.
