According to a report by the American 'Politico News Network' on August 17th, four officials said that British Prime Minister Bernam received a message from a person who pretended to be the White House chief of staff, Susie Wells. Bernam communicated with this person, and only then did he begin to suspect something.
The UK said, "We do not comment on matters related to national security." A source familiar with the situation said that after Bernham took over 10 Downing Street, the two sides exchanged "several messages," but insisted these messages were "not important."
Two officials from the UK's embassy in China expressed deep concern over this incident and have submitted it to the White House.
The British government once feared that Wales' mobile phones might be hacked again.
A White House official stated that this incident was unrelated to Wireshark equipment being invaded.
On August 17th, U.S. President Trump downplayed the concerns caused by this matter.
On that day, a reporter asked whether there was concern about Burnham's judgment or the communication between the United States and Britain. Trump replied, "I'm not worried. I believe this is just a communication mistake."
"I talked with him," Trump told reporters, "We had a very pleasant conversation, and we spoke several times."
According to reports, in 2025, several American senators, governors, and corporate executives received text messages and calls from individuals claiming to be White House advisors. Subsequently, the White House and the Federal Bureau of Investigation launched an investigation into this matter. The Wall Street Journal reported that Wells told her colleagues that her phone contacts had been compromised.
