GOP lobbyist Jack Burkman has been funding an investigation into Seth Rich's death, including "The Profile Project," an investigation by a group of George Washington University criminal justice students. Link He apparently believes Russia was behind Rich's death:

'The allegation is that Seth had discovered what the Russians were doing and that the Russians retaliated because of that discovery.

'Seth was in charge of all the tech guys and a whole technical aspect of voting at the DNC. He was the avant-garde of tech.

'It's very logical and very likely that if anyone would have discovered this [Russian hack] – Seth would have.'

Over the last six months, Burkman has been in touch with the DNC, including former chairwoman Donna Brazile. 'We have found the DNC to be very helpful,' he said.

Burkman says that during the election he started out pro-Trump but then became anti-Trump.
