NASHVILLE - Republican Randy Boyd says he will report raising more than $2.3 million for his 2018 gubernatorial campaign while injecting an additional $2 million of his own money into what is now a four-person GOP primary with still room to grow.

The Knoxville businessman and former state economic commissioner said in a news release that his campaign collected more than $4.3 million, including his own contribution, from March 1 through June 30.

Mid-year supplemental reports are due to the Tennessee Registry of Election Finance by midnight Monday.

"I am deeply grateful for the early and generous support from so many Tennesseans," Boyd said in a statement. "There are many ways to contribute and to help our campaign effort, but these early dollars from all 95 counties mean a lot and are a good indication of my commitment to campaign in and earn the support of every corner of our state."
