The $2.2 million total garnered between January and March is more than Brown raised in both previous quarters. In the third quarter of 2023, he brought in $1.1 million, and in the fourth quarter he upped it to $1.85 million.
Rosen's campaign did not reveal her fundraising for the first quarter of the election year or provide comment to Fox News Digital.
"Nevadans see through Jacky Rosen's pandering to the reality of her record: she consistently votes for open borders and reckless DC spending bills that skyrocket the cost of groceries and gas prices," said Brown spokesperson Kristy Wilkinson. "Nevadans are ready to replace her with Sam Brown's strong common-sense leadership."
The stakes in Nevada were raised on Wednesday when non-partisan race analyst the Cook Political Report shifted the race's 2024 rating from "Lean Democrat" to "Toss Up." The Nevada Senate race joins only three others in the category: Arizona, Montana and Ohio.
Brown's first quarter total is more than 2022 Republican Senate candidate Adam Laxalt pulled in at the same point in the midterm election cycle. Laxalt saw $1.6 million during January through March 2022. He ultimately lost to Sen. Catherine Cortez Masto, D-Nev.

Brown endorsed former President Trump in January, but Trump hasn't yet weighed in on the contentious Nevada Senate primary. However, Brown was a top recruit of the National Republican Senatorial Committee, chaired by Sen. Steve Daines, R-Mont., who quickly endorsed him. He has also been endorsed by Republican conference Chairman John Barrasso, R-Wyo. Other members of the Republican Senate leadership team have attended fundraisers for the candidate.
Grady did not release his fundraising to Fox News Digital, but hit Brown in a statement as "a wannabe career politician." According to the Republican candidate, Brown is trying to "buy himself a seat in Washington with the help of his big-donor friends."
"I am the only candidate meeting with Nevada voters face-to-face and hearing the issues important to them. Instead of focusing on the Washington-elite, I will continue to listen to Nevada voters," he added.
