Temer is under fire in the media and judiciary for controversially naming his close adviser Wellington Moreira Franco to a cabinet-level position.
That would give Moreira Franco -- reportedly implicated by a defendant in a giant embezzlement and bribery scandal -- protection from lower courts, with only the Supreme Court able to hear his case.
After a judge barred the nomination, the Supreme Court must now decide whether Moreira Franco can enter the government.
Temer yesterday went on national television to state that "the government does not want to shield anybody."

Several of Temer's closest allies in government and Congress and Temer himself have been named in plea bargain testimony by defendants in the corruption scandal centered on the Petrobras state oil company.
Temer himself allegedly asked for campaign finance funds from the giant Odebrecht construction company at the heart of a bribery scheme, according to leaked testimony. He denies any wrongdoing.
However, the president said that if any government members are actually charged with crimes, they would be suspended -- and in cases in which the Supreme Court decides to bring their cases to trial, "the suspension would be permanent."
