The phone calls Donald Trump Jr. made before and after his meeting with Russian operatives at Trump Tower during the 2016 presidential campaign were to NASCAR CEO Brian France and real estate developer Howard Lorber, ABC News reported.

Both men were supporters of Trump during the 2016 presidential campaign and have close ties to the president and his family.

The recipients of the calls remained a complete mystery until CNN reported Thursday that they were business associates of Trump Jr.

The calls fueled speculation that Trump Jr. may have told his father about the meeting prior to it happening — an accusation President Trump has denied.

France appeared at a campaign rally with Trump in February 2016 and boasted that he’d known then-candidate Trump for more than 20 years, according to the ABC report.

Lorber is even closer to Trump and served as an economic adviser on his campaign.

A spokesperson for Lober told ABC that he “does not recall having conversations with Donald Jr. in the summer of 2016, but in any event he has absolutely not had conversations with Donald Jr. about any Russian matters.”
