Washington (CNN) Secretary of State Mike Pompeo said Friday that the recent arrest of Yujing Zhang, the woman who allegedly breached security at President Donald Trump's private Florida club while carrying Chinese passports and a flash drive containing malware, is an example of the threat Beijing poses to the US.

Pompeo declined to provide additional details related to that claim during the interview on "CBS This Morning," but did say, "I think this tells the American people the threat that China poses, the efforts they're making inside the United States, not only against government officials but more broadly."

CNN reported on Wednesday that the FBI had begun investigating the possibility that the incident at Trump's Mar-a-Lago property was an espionage effort.

The US official who confirmed the espionage probe said the FBI is doing what it has to do in these circumstances, when there is a foreign national involved and a possibility of counterintelligence or cybersecurity issues.

Trump dismissed concerns about the incident when asked about potential Chinese espionage on Wednesday.
