In 2016, Trump had initially said that he would show his tax returns if he ran for president. He has since refused to release them since his election in 2016. He is the first president in four decades to withhold tax returns.
In a 7-2 ruling by the Supreme Court, Trump cannot hide his tax returns from Manhattan distrcit attorney Cy Vance. However, the Democrats will not have access to his tax records. Trump will not have to turn over his taxes in the Trump v. Mazars case. Subsequently, Congress will be unable to use the information against him politically. So, in essence, this was a political win for the President, as the public will not see what is in the records before the November election.
Legally however, this could be devastating for Donald Trump once he leaves office. In the Trump v. Vance case, prosecutors are attempting to determine if the Trump Organization violated any tax laws when making hush money payments to Karen McDougal and Stormy Daniels.
Regardless, of what happens in his New York case, this was surprisingly a net win for the Trump Campaigns 2020 bid for office. Any win is much needed for the campaign as public approval ratings have continued to plummet over his handling of the global pandemic.
