US media reported attempts to break into the cell phones of Republican presidential nominee Donald Trump, his running mate JD Vance, as well as members of Vice President Kamala Harris’s campaign.

Chinese hackers targeted phones used by US Republican presidential candidate Donald Trump, his running mate JD Vance and people associated with the Democratic campaign of Kamala Harris, US media outlets reported Friday.

Citing people familiar with the matter, the New York Times said Trump and Vance’s cellphones had been picked out by the hacking group and that investigators were working to determine what communications were taken, if any.

The revelation was also reported by the Associated Press, which cited its own anonymous sources.

Within a couple of hours of the first report, the Wall Street Journal reported that hackers had also targeted the phones of people associated with Democratic candidate Kamala Harris’ campaign.
