President Trump's lawyer blamed the U.S. Secret Service for allowing a Russian lawyer, Russian-American lobbyist and translator in to Trump Tower to attend a meeting with members of Trump's campaign.

"I wonder why, if this was nefarious, why the Secret Service allowed these people in," Jay Sekulow, the president's lawyer, said in an interview with ABC News on Sunday. "The president had Secret Service protection at that point, and that raised a question with me."

Donald Trump Jr., Jared Kushner, the president's son-in-law, and Paul Manafort, former Trump campaign chairman, met with Natalia Veselnitskaya, the Russian lawyer, at Trump Tower last year.

Trump Jr. said he met with Veselnitskaya after he was promised damaging information on Hillary Clinton, but no information was shared.

It was initially believed the only people in the meeting were Trump Jr., Manafort, Kushner, and Veselnitskaya. But on Friday, it was revealed a Russian-American lobbyist, Rinat Akhmetshin, and translator, Anatoli Samochornov, were also there.

Akhmetshin is believed to have ongoing ties to Russian intelligence operations.
