A bipartisan group of senators announced on Sunday that they will push for an investigative panel to look into allegations that Russia tried to manipulate the U.S. election by hacking into Democratic officials and groups' email servers.

Democratic Sens. Chuck Schumer of New York and Jack Reed of Rhode Island partnered with Republican Sens. John McCain of Arizona and Lindsey Graham of South Carolina in calling for the committee's creation.

The move comes after Democratic National Committee interim chairwoman Donna Brazile called for an independent bipartisan investigation into the organization's hacking problems.

Graham and McCain, both known as war hawks, have warned that these hacked emails, released by WikiLeaks, threaten America's democracy. Graham did not support President-elect Trump and has blamed President Obama for not doing more to prevent such hacking.

Incoming House Minority Leader Schumer called last weekend for a full investigation.

"The silence from WikiLeaks and others since election day has been deafening. That any country could be meddling in our elections should shake both political parties to their core," Schumer said.

The new effort puts pressure on Senate Majority Leader Mitch McConnell of Kentucky, who has indicated a preference for the Intelligence Committee to conduct an investigation.
