The hard-charging New York lawyer President Trump chose to represent him in the Russia investigation has prominent clients with ties to the Kremlin, a striking pick for a president trying to escape the persistent cloud that has trailed his administration.

Marc E. Kasowitz’s clients include Oleg Deripaska, a Russian oligarch who is close to President Vladimir Putin and has done business with Trump’s former campaign manager. Kasowitz also represents Sberbank, Russia’s largest state-owned bank, U.S. court records show.

Kasowitz has represented one of Deripaska’s companies for years in a civil lawsuit in New York and was scheduled to argue on the company’s behalf May 25, two days after news broke that Trump had hired him, court records show. A different lawyer in Kasowitz’s firm showed up in court instead, avoiding a scenario that would have highlighted Kasowitz’s extensive work for high-profile Russian clients

On Monday, Democratic gubernatorial candidate Beto O’Rourke made headlines when he announced at a campaign event that a billionaire was going to file a lawsuit against him. Sure enough, a defamation lawsuit against O’Rourke was filed in San Saba County later that day.

The man bringing the lawsuit against O’Rourke is Kelcy Warren, the co-founder and current Chairman of the Board of Directors at Energy Transfer Partners, one of the largest oil and gas companies in the world. His lawsuit is seeking damages against O’Rourke for defamation, slander, and libel.....

“There have to be very clear misstatements of fact, if there are merely opinions, generally speaking, they are not going to be actionable as defamation,” said Shavin. The standard of the law applies even further to a public official, according to Shavin. “It’s not enough just to prove it’s false or defamatory, it’s got to be proven that it was made with actual malice.”....

Shavin pointed to a Texas case to describe the very high bar for meeting defamation: Carr v. Brasher. In that case, the Texas Supreme Court denied rehearing a case from Lynn Brasher, the former mayor of South Houston, against his election opponent (and new mayor) Al Thiel and Walter Carr, a campaign aide who authored campaign brochures. Brasher alleged that Carr committed libel for some of those campaign brochures for an election in 1985. Some of the allegations raised in those brochures included “payoffs” Brasher made to bookkeepers. The defense for Thiel and Carr rested on the absence of “malice” in the accusation.
