Election officials in the United States are working to stop threats to the election system from cyber attackers. And Democrats in Congress are calling on the Federal Bureau of Investigation to investigate reports that Russia may be planning to try to affect the presidential election in November.

In a letter, the representatives said they want to know if the officials worked with Russia to carry out recent attacks against the Democratic National Committee and Democratic Congressional Campaign Committee to “interfere with the U.S. presidential election.
