Reps. Seth Moulton (D-Mass.) and Rep. Peter Meijer (R-Mich.) visited Kabul on Tuesday as evacuation efforts continued from Afghanistan.

Why it matters: They had not previously announced their trip, but said in a joint statement to news outlets that as Congress members they "have a duty to provide oversight on the executive branch." The State Department and U.S. military personnel had to "divert resources to provide security and information to the lawmakers," U.S. officials said, per AP.

Today with @RepMeijer I visited Kabul airport to conduct oversight on the evacuation.

Witnessing our young Marines and soldiers at the gates, navigating a confluence of humanity as raw and visceral as the world has ever seen, was indescribable. pic.twitter.com/bWGQh1iw2c
