WASHINGTON, MAY 25 (Xinhua) -- U.S. President Donald Trump on Thursday promised to probe into leaks of Manchester bombing investigation leads that have upsetted the United Kingdom.

"The alleged leaks coming out of government agencies are deeply troubling," Trump said in a statement issued by the White House.

"I am asking the Department of Justice and other relevant agencies to launch a complete review of this matter, and if appropriate, the culprit should be prosecuted to the fullest extent of the law," Trump said.

"These leaks have been going on for a long time and my administration will get to the bottom of this. The leaks of sensitive information pose a grave threat to our national security," Trump said.

The leaks of information on the Manchester bombing, days after Trump was accused of sharing sensitive intelligence from an ally with Russia, greatly irritated the British security community, which said the leak "undermined the investigation."

The White House has had trouble keeping secrets behind its doors since the beginning of Trump's administration, as a steady feed who did or said what in the White House found its way to the media.

The leaks have greatly damaged Trump and his team's credibility, especially in high profile cases such as the ongoing investigation into alledged collusion between Trump's campaign and Russia.

Trump have repeatedly vowed to patch up the porous White House, claiming national security is at stake.
