Fox News chief intelligence correspondent Catherine Herridge reported the latest moments ago on alleged attempts by Russia to meddle in the U.S. presidential election.

The FBI confirmed today it's aware of several hackings of GOP officials and surrogates, which come after successful cyberattacks on the DNC. 

An FBI official said he expects the rate of "probes, intrusions and attacks" to increase in the next few years, with hackers trying to achieve political objectives.

Rep. Michael McCaul (R-TX) said the FBI is working on "attribution" for the hacks, adding there were "certain conclusions" that he cannot discuss publicly. 

"I would hope they would, in the near future, come out very strongly about what Russia has done and what the response is going to be," he said. 

Moscow has denied involvement. 

Herridge said that if the White House assigns public attribution to Russia, or any nation, it would require some action as a punishment. 

Meantime, officials in Arizona and Illinois have said that there have been attempted hackings of voter registration systems. U.S. intelligence officials blamed Russian spy agencies.

Rep. Candice Miller (R-MI) said she believes that states should use paper ballots over computerized equipment.
