U.S. Senator Richard Burr, chairman of the Senate Intelligence Committee, said on Wednesday the need for improvements in security for the election system is “urgent.”

“This issue is urgent. If we start to fix these problems tomorrow, we still might not be in time to save the system for … 2020,” he said at a committee hearing on the issue, a day after it released draft recommendations on how to fix the system.

The next U.S. presidential election will take place in 2020.
