• McLain, of the Patriots for America PAC, is the brother of Paul Holzer, according to the ThinkProgress report. Holzer also has worked with the Brunner campaign.

• Holzer has been a business partner with one Jon Adkins, who is the founder of Draper Sterling, according to corporate records.

• In addition to paying Draper Sterling $35,000, the Trump campaign paid Adkins and Holzer $3,000 each, for “field consulting,” according to Trump’s records.

• Patriots for America — the PAC set up by Brunner’s other former staffer, McLain, to go after Greitens — has been hit with an FEC complaint, filed by a Greitens supporter, questioning why the PAC owes $56,234 to Draper Sterling for “business consulting.”

“To recap, there is a nexus between Jon Adkins, Paul Holzer and Adam McLain that meets at the mysterious Draper Sterling,” writes Judd Legum in the ThinkProgress piece that flagged the Trump expenditure.

“We still aren’t sure what Draper Sterling actually does, but these individuals are going to considerable lengths to obfuscate their activities.”

A Brunner spokesman said his campaign has had no contact with McLain or Holzer since September 2015.

In addition to Brunner and Greitens, Missouri’s GOP primary field includes former state House Speaker Catherine Hanaway and Lt. Gov. Peter Kinder. The winner of the Aug. 2 primary will likely face Democratic Attorney General Chris Koster in the Nov. 8 general election.
