Fresno County Deputy District Attorney Andrew Janz said the large influx of campaign funds came as Nunes failed to address the issues affecting his constituents. The Republican has been at the center of a political firestorm in recent months as he led his committee's efforts to probe alleged surveillance abuse at the Justice Department and the FBI.

"Devin Nunes is in Washington playing games on the House Intelligence Committee," Janz told CNN. "And while he is doing that the issues back here at home that people care about are being ignored."

The Janz campaign, which crossed the $1 million threshold with three days left in the first quarter of 2018, first saw a spike in contributions in the days after the committee released a controversial memo questioning the process by which the FBI and Justice Department approved a surveillance warrant on a former Trump campaign adviser Carter Page.

Despite the massive influx of cash, Janz still faces an uphill battle for California's 22nd district, which Ballotpedia has classified as "safe Republican." The Republican incumbent has more than $4 million in cash on hand for the upcoming race, according to the latest Federal Election Commission filings.
