House Speaker Mike Johnson (RLa.) is hosting a ceremony Tuesday to bestow the Congressional Gold Medal, the body’s highest honor, upon the 13 U.S. service members who lost their lives during the military’s withdrawal from Afghanistan in 2021.

The loss of their lives became politically charged, with Republicans assigning blame for the chaotic exit from the decadeslong Afghan conflict squarely upon President Biden. The Biden administration has maintained that it was following through on plans laid out by former President Trump.

The ceremony is slated to take place at 11 a.m. EDT.
