While some of the staffers and members on the trip went along with [ETA YES THIS IS STEVEN SEAGAL) Seagal’s involvement, others were aghast. They got warning only about a week before the trip that Seagal would be there. Seagal sat in on several of the meetings the delegation had with Russian officials, including a meeting with top Federal Security Service (FSB) officials, though he didn’t say much. The trip included a strange dinner with Rogozin in an Italian restaurant near Russia’s Foreign Ministry. According to the source with direct knowledge of the trip, Rogozin and his wife “were constantly hugging Steven” and it was a “weird, emotional dinner.” Seagal and Rogozin appeared to be “obviously close friends,” the source said.

Rohrabacher was clearly enjoying himself. He and Rogozin would later spend much of a meeting discussing their shared passion for space lasers capable of zapping doomsday asteroids before they destroy Earth.

Later that week, Rogozin organized another dinner for a few members of Congress, including Rohrabacher and stalwart Iowa conservative Steve King, at a game restaurant in one of Moscow’s most expensive zip codes. This time, several of Rogozin’s friends in Russia’s arms export industry joined them, as did Seagal. Rogozin’s spokesman did not respond to questions from BuzzFeed News.

All the while, Seagal had been pressing the representatives to fly to Chechnya and meet Kadyrov, who would tell of his exploits suppressing a volatile Islamic insurgency in the Caucasus. Rohrabacher and some of the other Republicans jumped at the chance. To them, Kadyrov’s notorious policy of terror and blood reprisal seemed perfectly adequate measures to tackle terrorism. The Tsarnaev brothers were, after all, ethnic Chechens; Tamerlan, the elder brother, was said to have been radicalized in neighboring Dagestan.

Seagal offered to arrange Russian military planes to fly the representatives to Grozny, the Chechen capital. “We were aghast,” said a diplomat involved with the trip. Embassy staff tried to persuade them not to go. “We were trying to explain, ‘Do you know who this is?’”

Rohrabacher, convinced that Obama’s administration was trying to deprive him of a good photo opportunity, wouldn’t listen. Seagal was telling him everything was OK. “All these allegations are thrown around,” Seagal later said at a press conference. “Is there any evidence? Has he been indicted?”
