Kathy Griffin had some sharp words for Michael Moore on Thursday, after “Fahrenheit 11/9” filmmaker implored the left to “Stop hoping & start acting!”

In a tweet published Thursday, Moore made an apparent reference to Supreme Court nominee Brett Kavanaugh, who became the subject of an FBI investigation due to a sexual misconduct accusation leveled against him by Christine Blasey Ford.

With Sen. Jeff Flake, who supported the probe, saying Thursday that the report on the FBI investigation showed “no additional corroborating information” against Kavanaugh, Moore took to Twitter criticizing “Dems & ‘liberals'” for “foolishly placing their hopes in the FBI.”

“Five days ago Dems & ‘liberals’ did the same old thing, claiming some empty ‘victory’ when Flake feigned shame, and then foolishly placing their hopes in the FBI – THE FBI! – doing an ‘investigation,'” Moore wrote.

“When is our side going to wake up and start FIGHTING? Stop hoping & start acting!” he added.

To which Griffin replied, “Michael…WE LOST.” “What more could we have done? We don’t have the Senate or the Presidency. What more can we do for god sakes?”

She added, “We should focus on the midterms but stop criticizing without a real world solution.”

As a final jab, Griffin asked, “And frankly what were you doing?”
