Burnham exchanges messages with impersonator posing as Trump's chief of staff, sparking security review

UK political figure Andy Burnham reportedly exchanged a small number of messages with someone claiming to be White House Chief of Staff Susie Wiles; officials said the contact was illegitimate and quickly reported to authorities. Downing Street declined to comment as the incident is reviewed, in a context of past impersonation and hoax attempts targeting UK and US officials, with the FBI previously probing Wiles' phone and other ministers' numbers having been exposed. No broad data breach evidence has been disclosed.
