Senate Minority Leader Chuck Schumer (D-NY) on Monday called for ousted Secret Service Director Randolph “Tex” Alles to testify before Congress concerning what Schumer called “potential security vulnerabilities” at President Donald Trump’s Mar-a-Lago club “and other counterintelligence and national security threats.”

Read Schumer’s statement below:

“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. 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’s properties.”
