The cases aren't directly tied to the ongoing House impeachment probe, which centers on Trump's push to have Ukraine announce investigations that could help him politically.
President Donald Trump on Thursday asked the U.S. Supreme Court to keep his financial records out of the hands of a Democratic-led congressional panel, setting up a major clash between branches of government.
The case is an important showdown before the US Supreme Court regarding the powers of the presidency compared to those of the Congress.
The case revolves around Mazars USA, Trump's accounting firm.
Trump argued Thursday that "under the D.C. Circuit's decision, Congress can subpoena any private records it wishes from the President on the mere assertion that it is considering legislation that might require presidents to disclose that same information".
The lawyers of the Republican president say that the committee is not authorized to carry out what they call a prosecution investigation.
The committee said it needs Mazars' records to determine if the government disclosure laws should be modified.
The justices make a choice up already shielded the paperwork from being turned over whereas they provide conception as to whether to listen to Trump's case and his separate attraction of a court docket order that requires the identical accounting firm to give his tax returns to the The huge apple District Attorney. The Supreme Court will consider whether to take up that case at a December 13 private conference.
In a third case, the New York-based appeals court on Tuesday directed Deutsche Bank AG and Capital One Financial Corp to comply with different subpoenas from congressional Democrats demanding similar material.
Trump's lawyers say the primary objective is law enforcement, something they say is beyond Congress's legislative powers. As the court has already blocked the similar decision of Mazars, it would probably grant this request.
The court has a 5-4 conservative majority that includes two Trump appointees: Neil Gorsuch and Brett Kavanaugh.
Both cases of Mazars are likely to be in a fast lane, meaning that if the court decides to hear it, a decision will be possible before the end of June, when the current term ends.
