Democratic Congressional Campaign Committee Targeted by Cyber-Attack, Official Says "[S]imilar to other recent incidents, including the DNC breach," official says.

 -- The FBI is investigating a cyber attack on the Democratic Congressional Campaign Committee that officials suspect may have been linked to another attack on the Democratic National Committee, ABC News has learned.

The DCCC's national press secretary Meredith Kelly confirmed the attack on Friday.

"The DCCC can confirm that we have been the target of a cybersecurity incident," Kelly said in a statement to ABC News.

An investigation into the attack is ongoing but investigators have said "this is similar to other recent incidents, including the DNC breach," Kelly said, referring to the recent hack of the DNC.

The DCCC is working with federal law enforcement in further investigating the matter, Kelly said. The DCCC has also hired outside forensic experts at CrowdStrike to investigate.

The DCCC, the official campaign arm for House Democrats, is the main fundraising organization for Democrats running for election in the House of Representatives.
