Trump's personal banking information handed over to Robert Mueller
The new revelation makes it clear that Mueller and his team are investigating the president’s financial transactions. It is not clear whether Mueller is interested in the bank accounts because they are connected to the Russia probe or if he is investigating another matter.
...Trump has consistently denied any collusion between his campaign and Russia and has stated that he did not have any business dealings in Russia. Since then, news has emerged that the Trump Organization sold a significant number of its properties to Russian clients and explored opening a hotel in Moscow, though the plan never came to fruition.
...Mueller’s investigators have, according to previous media reports, examined Russian purchases of Trump-owned apartments, the president’s involvement with Russian associates in a development in SoHo, New York, and the president’s 2008 sale of his Florida mansion to a Russian oligarch, Dmitry Rybolovlev.
So much for the admin's claims that the investigation was winding down and would be finished by Christmas, I guess.
