The justices split 5-4, with new Justice Amy Coney Barrett in the majority, her first publicly discernible vote as a justice.

It's not clear what legal issues might cause the justices to step in, while Chief Justice John Roberts is not likely to want the election to come down to the high court.

Twitter hid Trump's tweet behind a notice saying "some or all" of its content "is disputed and might be misleading about an election or other civic process."

The two cases Barrett will hear Monday are relatively low-profile, a dispute involving the Freedom of Information Act and another involving disability benefits for railroad employees.

Barrett was confirmed Monday by the Senate in a 52-48 virtual party line vote.

Barrett's confirmation on Monday was hardly in doubt, with majority Republicans mostly united in support behind U.S. President Donald Trump's pick.

Senate Majority Leader Mitch McConnell said he will begin the process as soon as the Senate Judiciary Committee wraps up its work Thursday.

The justices will not hear either new case until 2021, and the outcome of the presidential election could make the cases go away, or at least reduce their significance.

During Wednesday’s hearing, Barrett maintained her view that it would be inappropriate to comment on the national health care law or other cases that may come before her as a justice.

Barrett’s confirmation to the Supreme Court to take the seat of the late Justice Ruth Bader Ginsburg seems inevitable, as even some Senate Democrats acknowledged in Senate hearings on Tuesday and Wednesday.
