US President Donald Trump and his officials were the "likely" targets of a suspected gunman who attempted to storm the White House Correspondents' Dinner, acting US Attorney General Todd Blanche has said, BBC reported. 

The suspect, named by US media as 31-year-old Cole Tomas Allen, was arrested after police said he opened fire near a security checkpoint during the event at a Washington DC hotel on Saturday.

Blanche, speaking to NBC News, said the alleged gunman's motive is still under investigation, but that "preliminary" findings suggest he was targeting administration officials.
