Democrats on the House Administration committee called for “immediate congressional action” to shore up the security of U.S. elections following the indictment Friday of a dozen Russian officers accused of hacking election-related technology.

The Democrats also accused the GOP of ignoring their request to add more money to the already hundreds of millions of dollars approved for bolstering election security.

"Today's indictment underscores the need for immediate congressional action to secure our elections,” House Administration ranking member Robert Brady, D-Pa., and Rep. Jamie Raskin, D-Md., said. “We know that state-sponsored Russian intelligence officers targeted our election systems to disrupt our democracy. Despite this, the Republican Congress has done little to protect against a repeat attack in 2018.”

In March, Congress passed a 2018 spending package that included $380 million for states to replace paperless voting machines. Democrats want the GOP to pass legislation providing $1.8 billion over ten years to further upgrade election voting systems nationwide.

The lawmakers said “It is baffling” Republicans rejected adding more money for election security in fiscal 2019 spending legislation.

Republicans on the panel have not yet responded to the criticism from Democrats.
