LAS VEGAS (AP) — Attorneys for President Donald Trump’s reelection campaign and representatives of Nevada’ six Electoral College delegates for President-elect Joe Biden inspected voting materials Tuesday at the main Clark County elections office in suburban Las Vegas.

The visit to the ballot-counting center in North Las Vegas came ahead of a hearing scheduled Thursday before state Judge James Russell in Carson City in a contest-of-election case filed by the Trump campaign.

Jesse Binnall, a lawyer heading the Trump challenge of the Nevada election, has said he intends to prove that fraudulent votes were cast and that Trump won the state, not Biden. Binnall did not immediately respond Tuesday to messages about the election office inspection.

The Nevada Supreme Court has certified the election results as official, including Biden’s 33,596-vote statewide win over Trump in a coronavirus-inspired vote-by-mail push to avoid crowds at polling places.

Attorneys representing Registrar of Voters Joe Gloria and the state and national Democratic parties did not oppose the site visit.

Russell noted in a Monday court order that state law allows inspection of testing reports and materials “pertaining to the equipment and programs used” in election.

States face a deadline to resolve election disputes before the presidential Electoral College votes on Dec. 14.
