WASHINGTON — The headquarters of the Republican National Committee in Washington was briefly evacuated Wednesday morning after a suspicious package containing two vials of blood was delivered to the building, the police said. 

The RNC, the parent organization of the Republican Party, is playing a major role in the campaign of former President Donald Trump, who will face Democratic incumbent Joe Biden in the November 5 presidential election.  

The authorities initially closed off one downtown block and directed staff and other personnel to avoid the area. By midmorning, employees were reentering the building and police were leaving the scene, according to a Reuters witness.  

“The source of the package and its contents will be further investigated,” the U.S. Capitol Police said in a statement. 

The RNC did not respond to a request for comment.
