Meanwhile, the courts three liberal justices expressed concerns over a president shielded from accountability for criminal conduct.
The latter line is also a major Trump campaign theme.
But some of the justices saw the argument a different way.

It would depend on the hypothetical.
We can see that could well be an official act, Sauer said.
The justices will consider whether his conduct as president gives him broad immunity from prosecution.
The American people deserve to hear all of the J6 evidence presented in open court.
SCOTUS should conclude without delay that no immunity applies here.
And that could allow a second-term President Trump to quash the case.
Arguing for Trump will be John Sauer, the former solicitor general of Missouri.
The appellate court, in a unanimous decision, ruled that Trump did not have immunity.
In New York, Trump told reporters this morning, A president has to have immunity.
If you dont have immunity, you just have a ceremonial president.
