WASHINGTON — Hours before he was to help commission a new aircraft carrier at a patriotic ceremony on the Virginia coast, President Donald Trump fired off a volley of early morning tweets that again showed how furious he remains over multiple investigations into Russian meddling in the 2016 presidential election.

The tweets were unusual in their breadth and scope, even for Trump, given the wide variety of topics he touched on as Saturday dawned. His 10 tweets, all sent within two hours starting before 6:30 a.m., ranged from the Russia investigation and Attorney General Jeff Sessions to Hillary Clinton, the health care effort and his newly appointed White House communications director.

Trump said in one missive: “While all agree the U. S. President has the complete power to pardon, why think of that when only crime so far is LEAKS against us. FAKE NEWS.”

The Washington Post recently reported that Trump has inquired about the authority he has as president to pardon aides, relatives or even himself in connection with the widening investigation into Russian interference in the election and whether any Trump associates were involved.

The president has long criticized leaks of information about the investigation and has urged authorities to prosecute leakers.

Trump maintains that no crimes have been committed.
