One of the Trump cases is his appeal of a lower court ruling allowing a New York grand jury to subpoena his accounting firm Mazars LLP for his records.
Trump’s attorneys said prosecutors could be encouraged to investigate a president to advance their careers or score political points if that subpoena is enforced.
Another case concerns a lower court decision in Washington that endorsed subpoenas issued by the Democratic-led House Oversight Committee to Mazars.
Trump’s lawyers say there was no legislative purpose for the subpoenas and that the aim was merely to dig for dirt on the president.
In the third case, the justices will review a lower court ruling allowing the enforcement of separate House committee subpoenas targeting Trump-related financial records from Deutsche Bank AG (DBKGn.DE) and Capital One Financial Corp (COF.N).

The court on Friday extended its hold on the lower court ruling, which it had temporarily blocked last week.
The lower court rulings in the congressional cases, if left intact, would bring House Democrats closer to getting some of the details about Trump’s business interests.
That outcome would also amount to a major blow for the president, who, unlike past presidents, has refused to publicly disclose his tax returns.
Legal experts say the justices often hear cases when the president asks them to, but that does not mean Trump will ultimately prevail.
