The Supreme Court on Tuesday appeared likely to reject President Donald Trump’s claim that he is immune from criminal investigation while in office. But the court seemed less clear about exactly how to handle subpoenas from Congress and the Manhattan district attorney for Trump’s tax, bank and financial records.

The court’s major clash over presidential accountability could affect the  2020 presidential campaign, especially if a high court ruling leads to the release of personal financial information before Election Day.

The justices heard arguments in two cases by telephone Tuesday that stretched into the early afternoon. The court, which includes six justices age 65 or older, has been meeting by phone because of the coronavirus pandemic.

There was no apparent consensus about whether to ratify lower court rulings that the subpoenas to Trump’s accountant and banks are valid and should be enforced. The justices will meet by phone before the end of the week to take a preliminary vote on how those cases should come out, and decisions are expected by early summer.

On the same day Trump’s lawyers were telling the court that the subpoenas would be a distraction that no president can afford, Trump found the time to weigh in on a long string of unrelated issues on Twitter, about Elon Musk reopening Tesla’s California plant in defiance of local authorities, the credit he deserves for governors’ strong approval ratings for their handling of the virus outbreak, the anger Asian Americans feel “at what China has done to our Country,” oil prices, interest rates, his likely opponent in the November election and his critics.

The justices sounded particularly concerned in arguments over congressional subpoenas about whether a ruling validating the subpoenas would open the door to harassing future presidents.

“In your view, there is really no protection against the use of congressional subpoenas for the purpose of preventing the harassment of a president,” Justice Samuel Alito said to Douglas Letter, the lawyer for the House of Representatives.

Justice Stephen Breyer said he worried about a “future Sen. McCarthy,” a reference to the Communist-baiting Wisconsin senator from the 1950s, with subpoena power against a future president.

But in the case involving Manhattan District Attorney Cyrus Vance Jr.’s subpoena for Trump’s taxes, the justices showed little interest in the broadest argument made by Jay Sekulow, Trump’s lawyer, that a president can’t be investigated while he holds office.
