They could ruin the Trump Corporation if they wanted to.
If the good guys couldn't crack the Hillary fund raising scheme, then nobody is going to crack Trump's empire.
Hillary Clinton's fundraising scheme was being protected by the assets of the United States, including the State Department, the CIA, and the FBI.
President Trump has what on his side? He already has the rogue federal prosecutors at the SDNY after him, and leakers in the IRS and NSA.
In a war of attrition, he loses.
