As we are all aware, Donald Trump is fighting tooth and nail to prevent investigations by the Democratic Party controlled house, ignoring subpoenas and challenging any attempt at information gathering in court.

It looks like Congressional and New York State investigators have done an end run of his obstruction by demanding documents from his  partners:

Major Wall Street banks have given congressional committees investigating President Trump thousands of pages of documents related to Russians who may have had dealings with Mr. Trump, his family or his business, people familiar with the congressional probes said. Some banks are also giving documents related to Mr. Trump’s business, the Trump Organization, to New York state investigators, people familiar with the New York investigation said.

Wall Street firms including Bank of America Corp. , Citigroup Inc., Deutsche Bank AG , JPMorgan Chase & Co., Morgan Stanley and Wells Fargo & Co. have recently provided the documents to congressional investigators, according to people familiar with those probes. The investigators are working on a joint probe into potential foreign influence on Mr. Trump and his family by the House Financial Services Committee and the House Intelligence Committee. More information will likely be handed over in coming weeks as the banks continue to respond to subpoenas sent in April, the people said.

Separately, Deutsche Bank, Mr. Trump’s primary bank, has turned over emails, loan agreements and other documents related to the Trump Organization to the office of New York Attorney General Letitia James, in response to a civil subpoena sent earlier this year, according to people familiar with the New York investigation.

Ms. James’s office has also in recent weeks received financing documents and emails from Investors Bancorp Inc., the people said. The Short Hills, N.J., regional bank handed over thousands of pages in response to a civil subpoena demanding information on a 2010 mortgage on Trump Park Avenue, a condominium building in Manhattan owned by Mr. Trump, the people said.

Mr. Trump has filed several lawsuits seeking to block lawmakers and states from getting access to his bank, accounting and tax records. The documents being provided by the banks could give investigators some of the same information Mr. Trump is trying to block.

Of course, particularly with Pelosi running the show, I expect Democrats to squander this opportunity.
