Supreme Court Justice Sonia Sotomayor has faced calls from some on the left to resign before President-elect Donald Trump takes office.

Those demands have been prompted by fears over who Trump might nominate as the 70-year-old's replacement should she step down or pass away.

Judge Andrew Oldham slams political prosecutions

CNN recently examined some of the possible candidates, with one of them being Judge Andrew Oldham, who sits on the United States Court of Appeals for the Fifth Circuit.

The news network noted how Oldham, who was appointed to the Fifth Circuit by Trump in 2018, spoke earlier this month at a convention hosted by the conservative Federalist Society.

Although Oldham did not reference either the president-elect or Special Counsel Jack Smith by name, he did condemn "prosecutions lodged in the middle of political campaigns."

"One thing that is beyond reasonable debate is that people should not be prosecuted on the basis of their politics or on their status as a political candidate," the judge declared.

Judge James Ho: Birthright citizenship does not apply to "invading aliens"

Also present at the event was Judge Neomi Rao, who Trump put on the U.S. Court of Appeals for the District of Columbia Circuit.

CNN reported that she at one point proposed a toast to a series of Supreme Court rulings which weakened the authority of federal agencies.

The convention came just days after fellow Trump appointee Judge James Ho raised doubts over the 14th Amendment's right to birthright citizenship.

During an interview with South Texas College of Law Houston professor, Ho insisted that there is "a direct connection between birthright citizenship and invasion."

"No one to my knowledge has ever argued that the children of invading aliens are entitled to birthright citizenship," Ho declared before adding, "And I can't imagine what the legal argument for that would be."

Law professor: Trump wants "fearless judges"

Although CNN stressed that Trump has given no indication that he plans to elevate either Oldham, Rao, or Ho to America's highest judicial body, one observer says they have qualities he finds attractive.

George Washington University Law School professor John P. Collins Jr. told the network that Trump is "going to be looking for what I think some people call fearless judges – those who are not afraid to stake out their position and defend it and in theory take the criticism."

"Trump's picks during his first term all fit the mold of establishment legal conservatives. Now, they’re looking for more culture war-type conservatives," Collins added.
