State of the Union with Jake Tapper and Dana Bash

First Jake goes one-on-one with GOP presidential candidate Ron DeSantis, who responds to the final Des Moines Register poll showing him trailing significantly behind Trump and Haley ahead of the Iowa caucuses. Jake presses DeSantis on what a third place finish in Iowa would mean for the rest of his campaign and asks DeSantis if he underestimated Trump's grip on the Republican Party. Next, Jake interviews Vermont Independent Senator Bernie Sanders about the humanitarian crisis in Gaza and his push to restrict US military support for Israel. They also discuss US strikes against the Houthi rebels in Yemen and how Biden's handling of the situation in the Middle East will impact Biden's support among young voters in the election. After, CNN Senior Political commentator David Axelrod and former Maryland Republican Governor Larry Hogan join Jake to preview what they think will happen in the GOP Iowa caucuses. Then, our panel breaks down the Des Moines Register Iowa poll and what the outcome of the caucuses could mean for the rest of the GOP primary. Finally, Jake digs into Trump's most brazen argument in the January 6 case against him.
