Donald Trump is involved in another lawsuit. According to a Feb. 19 Reuters report, Trump has threatened to sue Angelo Carusone, the organizer of a Macy's boycott against him.

Carusone started an online petition on urging Macy's to cut all partnerships with the television personality.

"Macy's: Donald Trump does not reflect the 'magic of Macy's.' We urge you to sever ties with him. Macy's says it has a strong obligation to be 'socially responsible' and that 'actions speak louder than words.' Indeed. It's time to act," the petition read.

Donald Trump's attorney, Alan Garten, sent Angelo Carusone a cease-and-desist letter on Dec. 27, after mobile billboards appeared around Macy's Herald Square store and corporate headquarters in Cincinnati urging the company to restore the "Magic of Macy's."

Garten reportedly sent Carusone a letter after mobile billboards appearing around Macy's Herals store and corporate offices in Ohio urging the company to restore the "Magic of Macy's." The letter informed Carusone that Trump will sue him for damages of "not less than $25,000,000" if he continued his campaign against the business mogul.

"While you claim to be merely exercising or right to free speech, your egregious, pre-meditated and illegal conduct far exceeds anything protected by the Constitution," the letter, dated Dec. 27, read. "Rather than simply engage in lawful protest, you have apparently made it your mission to interfere with and intentionally disrupt Mr. Trump's longstanding and well-established business relationship with Macy's as well as his contractual dealings with other third parties through mob-like bullying and coercion."

In a Jan. 23 response letter, Paul Alan Levy of Public Citizen, Carusone's attorney, challenged Garten's claims for his client.

"There is a well-established First Amendment right to advocate a boycott over policy-related objections ... I have no reason to believe that there is a tort of exaggerating the public support for a political campaign. If there were such a tort, I imagine that most candidates for public office, no doubt including your client, would be liable at one point or another," Levy wrote.

"Donald Trump does not reflect the 'magic of Macy's,'" Carusone wrote in the petition.

Reuters reported that since Carusone started his petition last year on, it gathered more than 683,000 signatures. Carusone, through the petition, pleaded that Macy's Chairman, CEO and President Terry J. Lundgren stop selling Trump's fragrance and clothing lines at Macy's stores, because of "especially unpleasant, nasty and despicable behavior," including "sexist behavior," and the President Barack Obama birth accusations made by Trump.
