Flor Cerrato, an accountant from Los Angeles in a pink Trump cap and red Trump mask, said she came to the protest because she believed that the president had “already won by landslide.”
“Why don’t they just let it go,” she said while holding a “Latinos-Americans 4 Trump” sign. “They’re trying to switch the numbers around.”
Republican leaders appeared at some protests reviving oft-used claims of irregularities that have in the past been debunked or shown to be greatly exaggerated. Outside a nondescript warehouse in North Las Vegas where most of the uncounted votes in Clark County remain, they erected a podium in the street.
Broadcasting on a hastily announced livestream, the former Nevada attorney general, Adam Laxalt, said Republicans had filed a lawsuit after discovering evidence of dead people and out-of-state voters illegally casting ballots in Nevada — but he did not provide any specifics to support those claims.
“We’re asking the judge to, due to all of these irregularities, to stop the counting of improper votes,” he said.
Mr. Laxalt was joined by Matt Schlapp, chairman of the American Conservative Union, and Ric Grenell, former acting director of national intelligence.
Dozens of flag-waving Trump supporters looked on, and trucks with Trump flags circled the block, some gunning their engines and honking their horns.
Mr. Grenell refused to answer questions, telling reporters, “Listen, you are here to take in information.” As reporters shouted questions, the speakers got into a van and drove away.
