They're not reporting anything, just essentially retweeting stuff from another guy who nobody knows.

That said, there IS evidence that Trump's team DID in fact use the Eisenhower Office as an election day war room. Dem Rep. Bill Pascrell, in fact, went to the Office of Special Counsel and requested an investigation be done, because using a government building to do "campaign activities" is a problem.

So there are bread crumbs here, but we don't know much else for real.
