Democrats continue to whine about Russia allegedly hacking into the Democratic National Committee’s computer servers and the impact that may have had on the election outcome, but they weren’t concerned enough to allow the FBI access to learn more about the intrusion.

That was the word Tuesday from FBI Director James Comey, who testified before the Senate Intelligence Committee in an open session on Russian interference in the U.S. election, according to The Hill.

More from The Hill:

The FBI requested direct access to the Democratic National Committee’s hacked computer servers but was denied, Director James Comey told lawmakers on Tuesday. The bureau made “multiple requests at different levels,” according to Comey, but ultimately struck an agreement with the DNC that a “highly respected private company” would get access and share what it found with investigators. “We’d always prefer to have access hands-on ourselves if that’s possible,” Comey said, noting that he didn’t know why the DNC rebuffed the FBI’s request.

The DNC disputes Comey’s assertion, with deputy communications director Eric Walker telling BuzzFeed in an email last week that the bureau never made such a request.

But a senior law enforcement official said the following day that’s not true, The Hill reported.

“The FBI repeatedly stressed to DNC officials the necessity of obtaining direct access to servers and data, only to be rebuffed until well after the initial compromise had been mitigated,” the official said.

“This left the FBI no choice but to rely upon a third-party for information,” they continued. “These actions caused significant delays and inhibited the FBI from addressing the intrusion earlier.”
