The top contenders in Nevada’s high-profile U.S. Senate race have finally agreed to a debate.

U.S. Rep. Jacky Rosen, D-Nev., and U.S. Sen. Dean Heller, R-Nev., on Monday issued dueling statements unveiling the Oct. 19 debate in Las Vegas. It will be hosted by KLAS Las Vegas (CBS), KTVN Reno (CBS) and Univision in Las Vegas and Reno.

News of the pair’s first televised tussle comes three months after Rosen first called for a trio of televised debates and one month after Heller agreed to two such events.

Rosen is yet to accept Heller’s invite to an Oct. 8 debate in Reno that would be aired statewide on NBC affiliates and Telemundo.

She wants a different host for the proposed Reno clash, citing a $1,000 donation KRNV Reno’s parent company, Sinclair Broadcast Group, made to the Heller campaign. In a statement, Rosen’s campaign suggested the debate be held in a town hall format hosted by either KNPB (PBS) or KOLO (ABC).

“There are major differences between how Jacky Rosen and Dean Heller will serve Nevadans in the Senate over the next six years, and this upcoming debate will illuminate the clear contrast in this race,” said Rosen for Nevada campaign manager Danny Kazin. “Nevadans across the state should hear directly from their candidates for U.S. Senate, and having fair hosts for these debates is critical to ensuring voters can properly evaluate the candidates and make that informed decision."

Heller’s camp fired back in a statement that accused Rosen of backing down from the event.

“It has been over a month since Dean Heller accepted invitations to debate in Reno and Las Vegas, and finally Jacky Rosen has chosen to answer the challenge,” said Heller campaign spokesman Keith Schipper. “While Heller looks forward to debating Congresswoman Rosen on October 19 in Las Vegas, it is inexcusable that she refuses to accept the debate on October 8 in Reno.”

Heller is considered the most vulnerable Senate Republican up for re-election in November. He is the only Senate GOP incumbent trying to hold his seat in a state won by Hillary Clinton.

Rosen, a first-term congresswoman from Henderson, is running her second-ever campaign under a national spotlight cast upon one of the most closely watched congressional races in the nation.

The pair will face off in a general election scheduled for Nov. 6.
