Panelists Katie Pavlich, Juan Williams and Guy Benson join "Special Report with Bret Baier" to discuss President Joe Biden's anticipated presidential reelection announcement and the possible "age issue." Rep. Ronny Jackson, who was a White House physician to multiple presidents, is circulating a letter among House Republicans demanding that President Joe Biden take a cognitive test or drop out of the 2024 race. Jackson, R-Texas, led previous calls for Biden to take a cognitive test, including one in July 2022 that was signed by more than 50 House Republicans. The latest letter comes as Biden is widely expected to officially announce his 2024 campaign this week. "We call on you to either resign immediately and renounce your bid for reelection or submit to a clinically validated cognitive screening assessment and make those results available to the public," says Jackson's letter, which is addressed to Biden.
