White House Says Trump 'Extremely Concerned' about WikiLeaks CIA Breach

President Donald Trump is "extremely concerned" about a security breach at the CIA that led to anti-secrecy group WikiLeaks publishing agency documents on its hacking tools, the White House said on Wednesday.

White House spokesman Sean Spicer said at a news briefing that the Trump administration intends to be tough on leakers.

"Anybody who leaks classified information will be held to the highest degree of law. We will go after people who leak classified information. We will prosecute them to the full extent of the law," he said.
