Meet the other father-son duo embroiled in the latest Trump-Russia scandal

They have ties to the Trump family.

Aras Agalarov and his son Emin Agalarov have become part of the saga in light of their connection and alleged involvement in the meeting between Trump Jr. and a Russian attorney. Their first names are mentioned in the email chain that Trump Jr. released showing the arrangement of his meeting with a Russian lawyer who he was told may have "information that would incriminate Hillary [Clinton] and her dealings with Russia and would be very useful to your father."

The pop star involved in political drama

Emin Agalarov is a singer from Azerbaijan and a vice president of his father's development company, the Crocus Group. In an email in the chain, Goldstone writes, "Emin just called and asked me to contact you with something very interesting."

"Emin and his father have a very highly respected company in Moscow," Trump Jr. said in the statement.

Emin Agalarov was born in Azerbaijan and moved to Moscow when he was 4 years old, according to his biography on the Crocus Group's website. The site also states that he is single and has two children.

He oversees a number of the company's properties, including two of its retail-entertainment complexes, a resort in Azerbaijan and a restaurant portfolio that includes outposts of the famed Asian chain Nobu, according to the company website.

Trump Sr. showed his fondness for Emin Agalarov on Twitter in 2013 after the Miss Universe pageant in Moscow, sending him a direct tweet that said, "Emin, your performance at Miss Universe was fantastic -- you are a STAR!"

Trump praised a "Today" appearance by Emin Agalarov the next year, calling him "a star!" again.

The picture of him in a car was captioned "Finally sunshine" with several sun emojis and then "What's new???" in Russian, which some are seeing as a nod at the unfolding saga in the U.S.

The mogul who found a fan overseas

Aras Agalarov is Emin Agalarov's father and a Russian real estate tycoon. He heads the Crocus Group.

Forbes estimated that Aras Agalarov is worth $1.92 billion.

According to The New York Times, the Crocus Group licensed the Miss Universe pageant from the Trump Organization in 2013 to host that year's show in the Russian capital.

The president has also tweeted at Aras Agalarov, writing in 2013, "I had a great weekend with you and your family. You have done a FANTASTIC job. TRUMP TOWER-MOSCOW is next. EMIN was WOW!"
