It's one thing to make an unsubstantiated claim, it is another to keep on claiming that Russia hacked the DNC when Crowdstrike President Ken Henry, testified before the House Intelligence Committee in 2017, and could not provide solid evidence that Russia or any other group, hacked and stole the DNC emails.

Aaron Mate writing for Real Clear Investigations, reported that Henry had little evidence, was making assumptions, and didn't even have a record of the files leaving the system.

The real conspiracy here is that Rep Adam Schiff, knowing full well the testimony existed, chose to sit on the Henry testimony until it was uncovered in 2020. This deception may have changed votes in the 2020 election.
