From Campaign Legal Center’s release:

Campaign Legal Center (CLC) has filed a lawsuit in District of Columbia federal court, challenging the Federal Election Commission’s (FEC) recent dismissal of an administrative complaint that CLC filed against the campaign committees of then-President Donald Trump in July 2020 and later supplemented in January 2021. 

The underlying administrative complaint alleged that Trump’s 2020 campaign violated federal campaign finance transparency requirements by funneling hundreds of millions of dollars in payments to campaign staff and vendors through firms affiliated with the campaign, thereby hiding the details of those payments from the public.
