House Republicans voted to block the release of an Ethics Committee report about allegations of sexual misconduct and illicit drug use against Matt Gaetz, President-elect Donald Trump's choice for attorney general, setting up a possible constitutional clash between the House and the Senate. Separately, federal investigators established a trail of payments made by Gaetz to women, including some who testified that he had hired them for sex, according to a document obtained by The Times and a lawyer representing some of the women.
