Donald Trump has asked the Supreme Court to reinstate a controversial citizenship registration system. The system, known as SAVE, is a Department of Homeland Security program that had been used to conduct thorough reviews of state voter rolls.

The use of SAVE for voter roll audits was largely suspended after a lower court found that the administration had violated privacy laws by expanding the program. Critics argue that the program produces inaccurate results, mistakenly identifying eligible voters as non-citizens.

Further details about the case and the controversy surrounding the SAVE program are available from the source.
