President Joe Biden has visited Walter Reed medical centre to meet with service members.
Mr Biden visited on Thursday evening after most events were finished. The White House did not disclose whether any of the service members the president had visited were injured in Kabul.
“Tonight, the president and first lady are visiting wounded warriors at Walter Reed National Military Medical Center,” the White House said in a statement.
The 20 service members who were injured during the explosion in Kabul that also killed 13 service members are all recovering at Walter Reed, Stars and Stripes reported this week.
The United States ended its military operations in Afghanistan on Tuesday. Mr Biden has faced criticism from both Republicans and Democrats over the pullout, which saw thousands attempt to leave Afghanistan as the Taliban swept to power in mere days in August.
Devastating images from Kabul airport showed crowds desperate to board planes out of the country, with at least 100 Americans and thousands of US allies remaining in the country after US military operations in Afghanistan ended.
