House Speaker Mike Johnson, Gov. Ron DeSantis, Liz Cheney & more.

This week on Face the Nation, we traveled to the U.S.-Mexico border for a firsthand look at what a growing number of Americans are calling a “crisis.” We share our conversation with the new Speaker of the House Mike Johnson at the border. As the Iowa caucuses approach, Republican presidential candidate Gov. Ron DeSantis shares his vision for how he would handle the border if elected. On the third anniversary of the January 6 attack on the Capitol, Liz Cheney reflects on that day and the current state of the Republican party. Plus - Sen. Chris Van Hollen joins us live from Amman, Jordan where he tells us about his visit to the Middle East.
