Last month, House Foreign Affairs subcommittee on Oversight and Investigation chairman Rep. Dana Rohrabacher (R-CA) met with WikiLeaks founder Julian Assange. This meeting led to a potential deal being brought to the White House by Rohrabacher.
Under this deal, which was reported by the Wall Street Journal, Assange would provide conclusive proof that Russia was not the source of hacked emails WikiLeaks published. In return, he would be offered a pardon, or some other assurance that he wouldn't be prosecuted by the US for involvement in WikiLeaks.
Rohrabacher brought this deal to the White House Wednesday, but Chief of Staff John Kelly not only apparently didn't like the offer, but didn't tell President Trump that the offer had been made, instead telling Rohrabacher to take the proposal to the intelligence community.
