The Lincoln Project, a political action committee founded by former Republican figureheads, is pledging to spend at least $500,000 on an advertising blitz vowing to “target” Jones Day and Porter Wright Morris & Arthur for their role as counsel to the Pennsylvania Republican Party and President Donald Trump respectively as they bring unsupported claims of voter fraud in the 2020 election.

“The law firms architecting Donald Trump’s unwarranted and dangerous attacks on our democracy are @JonesDay & @PorterWright. Their employees should resign in protest,” the organization wrote in one tweet, citing the New York Times report.
