(CNN) - Pennsylvania Republican Pat Toomey says his campaign for the Senate has raked in $1.6 million since he jumped into the race on April 15.
Toomey's campaign also announced Monday that more than 15,000 people from across the country have contributed and that as of the end of June, the campaign had $1.1 million cash on hand.
"I am honored by all the people who have contributed to my campaign since my announcement," Toomey said in a statement. "These contributions come from folks across all of Pennsylvania and the country who know that America has a better future than the runaway spending and endless bailouts that are coming from Washington today. Together, I believe we can bring fiscal responsibility, political balance, and economic growth back to our country."
The fiscally conservative Toomey is a former congressman and former head of the Club for Growth, a limited-government, anti-tax organization. Toomey nearly beat Senator Arlen Specter in the 2004 GOP primary.
Toomey was leading Specter in polls of a hypothetical Republican Senate primary earlier this year, before Specter switched his party identity from Republican to Democrat. Specter said then the difficulty in winning the Republican primary was a factor in his decision to switch parties.
