A private jet thought to be carrying another US congressional delegation has been denied permission to land at Kabul airport, a source familiar with the situation told CNN on Thursday.
The Gulfstream jet was visible over Turkmenistan on open-source air traffic websites, but its destination and final route were unclear. It was last seen over Baku, Azerbaijan, and departed from Athens, Greece.
It remains unclear which representative was on the jet.
On Tuesday two congressmen, Seth Moulton, a Democrat from Massachusetts, and Peter Meijer, a Republican from Michigan, made a clandestine trip to Kabul "to conduct oversight on the mission to evacuate Americans and our allies."
The decision was criticized by House Speaker Nancy Pelosi, who said: "We don't want anyone to think this was a good idea. There's a real concern about members being in the region."
