“The outgoing Secret Service director must testify before Congress as soon as possible about the potential security vulnerabilities at Mar-a-Lago involving a Chinese national arrested with malware, and other counterintelligence and national security threats," Schumer said in a statement.

"The public and Congress need to know the extent to which adversarial governments — like China — and their agents are attempting to gain access to, or conduct electronic surveillance on, conversations or other information regarding national security at President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE’s properties," he added.

White House press secretary Sarah Huckabee Sanders said earlier Monday that President Trump is removing Alles from his position as director of the Secret Service, adding that he will be "leaving shortly." His successor, James Murray, is expected to take over the position starting in May.

Schumer's statement comes after Yujing Zhang, a Chinese national, was arrested as she tried to enter Mar-a-Lago's pool. Federal prosecutors alleged in a filing last week that she entered the club with a thumb drive containing malicious software and multiple passports.

Federal prosecutors added at a hearing in Florida on Monday that she also had multiple USB drives, thousands of dollars in cash, a second cellphone and five SIM cards.

The Miami Herald reported that federal authorities are probing possible Chinese spying targeting Mar-a-Lago, Trump's private club in Palm Beach, Fla., including looking into Zhang.

But Trump downplayed concerns about security on the property last week, saying they had "very good control."
