U.S. Reps. Steven Horsford and Susie Lee, both Democrats, are maintaining tight leads over their Republican challengers in the race for two of Nevada's congressional seats.
Lee was ahead of Dan Rodimer, 171,834 votes to 165,033 votes, as of Thursday morning.
Her lead grew by 1,568 votes following the updated tally, per the Nevada Secretary of State's office.
Horsford held an advantage over Jim Marchant, 141,737 votes to 134,057. The divide between the two candidates grew by 983 votes on Thursday.
The races remain too close to call, with about 190,000 ballots still to be counted in Nevada, according to the Secretary of State.
Nevada's other two Congressional races have already been called by the Associated Press. Incumbent Reps. Dina Titus, a Democrat, and Mark Amodei, a Republican, are projected to win re-election.
