ROUGH CUT (NO REPORTER NARRATION) U.S. President Donald Trump said on Wednesday he was not worried about Chinese espionage at Mar-a-Lago, after the Secret Service arrested a Chinese woman who had passed security checkpoints at the Florida resort carrying a thumb drive with malicious software.

Chinese citizen Yujing Zhang talked her way past checkpoints into the exclusive Trump resort while the president was golfing nearby.

After Zhang got inside the resort perimeter, Mar-a-Lago and Secret Service personnel grew suspicious.

When she became aggressive under questioning, she was detained by the Secret Service and later charged with making false statements and entering a restricted area.

After detaining her, investigators found in Zhang's possession four cellphones, a laptop computer, an external hard drive device and a thumb drive, the Secret Service said in a court filing.

Initial examination of the thumb drive determined it contained "malicious malware," the Secret Service said.

Zhang's ability to get inside Mar-a-Lago without credentials or an appointment "raises very serious questions regarding security vulnerabilities," said Senate Democratic leader Chuck Shumer and senators Dianne Feinstein and Mark Warner, the top Democrats on the Judiciary and Intelligence committees.
