July 2 (UPI) -- Film giant Paramount Global reached a settlement with U.S. President Donald Trump, who sued CBS News for $20 billion over editing of a 60 Minutes interview with his Democratic opponent, then-Vice President Kamala Harris.

The move raises further concerns with press freedom and democracy advocates characterizing Trump's lawsuit as frivolous, a attack on the free press and unprecedented, while some Democrats warn it may violate bribery laws.

On Wednesday, Sen. Elizabeth Warren, D-Mass., called for a full investigation into if anti-bribery laws were broken, saying that Paramount has "refused to provide answers to a congressional inquiry," and revealed her intent to introduce a new bill to curb "corrupt" presidential library donations.

"With Paramount folding to Donald Trump at the same time the company needs his administration's approval for its billion-dollar merger, this could be bribery in plain sight," the Massachusetts Democrat said in a statement.

It comes a day after both sides of the lawsuit asked the court to stay ongoing proceedings in the case "because the parties are engaged in good faith, advanced, settlement negotiations," which the court agreed to on Tuesday.
