The Supreme Court on Friday agreed to take up three separate cases - all dealing with U.S. President Donald Trump's efforts to keep his financial records - including tax returns - out of the hands of Democrats and a New York prosecutor.
The court will hold oral arguments in March, with a decision due by the end of June - right in the midst of the 2020 presidential election.
The president is attempting to block subpoenas for bank records and other material demanded by Democratic-led committees in the House, as they investigate corruption and foreign meddling in the U.S. elections process.
The probes are unrelated to the impeachment proceedings playing out against the president over his dealings with Ukraine.
The cases will test the court's conservative majority and how the justices view Trump's arguments that the subpoenas are a threat to the presidency After the announcement, one of Trump's lawyers said in a statement that they are pleased and that the cases "raise significant constitutional issues."
