Left-leaning organizers have raised more than $160,000 for the future opponent of U.S. Sen. Chuck Grassley, should he choose to run again in 2022, according to a news release.

The money for the yet-to-be-named Democratic challenger has been raised via Crowdpac, a political crowdfunding website, by the "Be.A.Hero" group.

The group says Grassley, the chair of the Senate's Judiciary Committee, was "flippant" when Christine Blasey Ford testified about Supreme Court nominee Brett Kavanaugh's alleged sexual assault.

Grassley would be up for re-election in 2022 if he chooses to run again. The money for Grassley's future opponent is non-conditional.

Other groups, like the Iowa Coalition Against Sexual Assault, also criticized Grassley's handling of Kavanaugh's hearing. The coalition released a statement from its executive director, Beth Barnhill, that said her group is “furious” that the Senate Judiciary Committee voted Friday to advance Kavanaugh’s nomination to the full Senate.

Grassley's office announced several hours after the vote that the judiciary committee will request that the Federal Bureau of Investigation conduct a "supplemental background investigation" limited to "current credible allegations against the nominee" that must take no longer than one week. President Donald Trump later formally ordered the investigation.

The result of that investigation is expected this week.

Ady Barkan, an activist with Lou Gehrig's disease, started the crowdfunding efforts against Grassley and Collins. He was recently arrested in protests organized to support a "no" vote on Kavanaugh, according to the release.

Michael Zona, a Grassley campaign spokesman, said the crowdfunding effort is not a concern for Grassley.

"Sen. Grassley's never earned less than 60 percent of Iowans' vote in any of his six successful re-election campaigns," Zona said in a statement. "Extreme, left wing activists from out of state should feel free to waste their money on this lost cause. Meanwhile, Sen. Grassley is working harder than ever to represent Iowans."
