US President Donald Trump has reportedly fired the director of the US Secret Service.
Randolph Alles is one of several Department of Homeland Security (DHS) officials being ousted on Monday, says the BBC's US affiliate, CBS News.
Mr Alles' departure comes a day after DHS Secretary Kirstjen Nielsen tendered her resignation under pressure over the situation at the US-Mexico border.
Dozens of top officials have exited the Trump administration since 2017.
The White House confirmed Mr Alles would go, but did not say whether Mr Trump fired him.
