3:30 p.m. ET A Nevada judgefor an order to isolate ballots in Clark County that were allegedly cast after polls closed, dismissing a suit that could have also affected the state’s close Senate race.
At an emergency hearing Tuesday afternoon, Judge Gloria Sturman said the Trump campaign’s lawsuit raises privacy concerns for the poll workers whose identities the campaign was requesting, saying she feared they would be the subject of “harassment.” Sturman also said Clark County officials are already required to preserve the records the Trump campaign was asking to preserve.
“I am not going to issue any order,” Sturman said.
The Trump campaign filed suit against the Clark County registrar, accusing him of intentionally coordinating with Democratic activists “in order to skew the vote unlawfully in favor of Democratic candidates.”

Schumer is expected to be the next Democratic leader with Harry Reid’s retirement, and could potentially become majority leader.

11:30 a.m. ET Across the country, voters aren’t just deciding who will win the White House Tuesday -- they’ll also be deciding the fate of 34 seats in the U.S. Senate.
