Sen. Jacky Rosen raised almost $550,000 between the beginning of the year and the end of March, the most raised by any member of the congressional delegation in the first quarter of the year. Rep. Susie Lee raised the second-highest total with nearly $450,000.

Elected in 2018 and up for re-election in 2024, Rosen defeated former GOP Sen. Dean Heller in 2018, in one of the nation’s most closely watched Senate races. During her campaign last year, she raised $7.1 million between July and September.

While the first quarter reporting period runs from Jan. 1 through March 31, the Federal Election Commission requires finance reports to be filed by April 15.

Of $546,628 Rosen raised, $216,092 came from individuals, while $65,000 was provided by political action committees (PACs) not directly related to the political parties. Those included the National Association of Realtors PAC, which gave $5,000, as did the Wynn Resorts Ltd. Initiative for Public Policy. She reported a transfer of $29,500 from the Rosen Victory Fund.

Her campaign reported ending the first quarter with $501,997 on hand.

Rosen’s haul was more than double raised by her Senate counterpart Catherine Cortez Masto who received $192,000 in the first quarter. Nevada’s senior senator is not up for re-election until 2022. First elected in 2016, she won a tight race against former Republican Rep. Joe Heck in order to take the seat previously held by Democratic Leader Harry Reid.

Cortez Masto raised $366,521 in the previous quarter. Of the $192,000 Cortez Masto raised, $153,305 was raised from individuals and $10,500 came from non-Party PACs.

The Nevada Democrat’s campaign reported ending the first quarter with $1.02 million on hand.

In the House, Rep. Susie Lee, who represents the Third Congressional District, raised $448,090. Lee is in her first term and is a target for Republicans in 2020. Her seat has a history of flipping between the parties and was won by President Donald Trump in the 2016 election.

Most of the contributions, $302,077, came from individuals. Another $135,500 came from non-Party PACs. Some PACs contributing to Lee’s campaign in the first quarter include MGM Resorts International PAC, which gave $5,000 and $2,000 from Nancy Pelosi for Congress, the speaker’s campaign fund.

Lee’s campaign reported ending the first quarter with $408,373 on hand.

Rep. Steven Horsford reported raising $371,389 over the same period. The Fourth Congressional District representative, who held the post for one term between 2013 and 2015, is also a target for Republicans who see his seat as a pickup opportunity.

He raised much of the funds, $248,500, from non-Party PACs, including the Home Depot Inc. PAC, which gave $5,000. Individuals were responsible for $122,889.

Horsford’s campaign ended the quarter with $309,876 on hand.

Rep. Dina Titus, who represents the First Congressional District that has never been represented by a Republican, raised $118,867.

Of that figure $74,366 was raised by individuals and $44,501 from non-Party PACs. Titus reported ending the quarter with $245,478 on hand.

Republican Rep. Mark Amodei reported raising $49,060 in the first quarter. The Second Congressional District representative reported that $13,399 came from individuals and $34,000 from non-Party PACs. At the end of the quarter, Amodei had $229,612 on hand for the district that has always been held by a Republican.
