Story highlights Trump Jr., a Russian lawyer and top members of Trump's campaign took part in the meeting

The President has maintained having no knowledge of the meeting

Washington (CNN) The Secret Service is pushing back on President Donald Trump's attorney's remarks Sunday that there was nothing questionable going on at a meeting last summer between Trump's eldest son, Donald Trump Jr., a Russian lawyer and top members of Trump's campaign.

"Well, I wonder why the Secret Service, if this was nefarious, why the Secret Service allowed these people in," Jay Sekulow said on ABC's "This Week. " "The President had Secret Service protection at that point, and that raised a question with me."

After Sekulow's comments aired, the Secret Service responded that it wouldn't have checked out the participants of the meeting because Trump's eldest son wasn't in their charge.

"Donald Trump Jr. was not a protectee of the USSS in June, 2016," the agency told CNN in a statement. "Thus we would not have screened anyone he was meeting with at that time."
