(CNN) - Arizona Gov. Jan Brewer questioned the timing of recent reports that she was involved in a 1988 alcohol-related car accident, blaming opposition to her candidacy in the final days of a tight race for her first full term as governor.
"It's interesting that so much stuff rises to the top for whatever the reasons, but yeah it's the silly season, I think people are digging and trying to discredit different candidates not only here in Arizona but certainly across Arizona," Brewer told CNN Chief National Correspondent John King in an interview set to air Thursday on John King, USA at 7 p.m. EST.
The Arizona Republic reported Wednesday night that Brewer – then a state senator – was involved in a minor fender bender over two decades ago, and that officers at the scene believed she was intoxicated.
Brewer has maintained that she did not believe that she was impaired.
"I had gone to dinner with some legislators, had dinner and had a couple of glasses of wine and was driving home on I-17 which is a free way in Phoenix and it was a construction zone," Brewer told CNN.
"We were traveling at very slow speed and I rear-ended the car that was in front of me. The Department of Public Safety was called, and they determined by their investigations, if you will, that they were going to detain me. I believe that I was not impaired," Brewer said.
Though Brewer was detained briefly, she was never charged in the crash. The state of Arizona protects lawmakers from arrest during the legislative session, although charges could have been filed after the session ended, according to the Arizona Republic. The Republic has questioned whether Brewer might have received special treatment from the Department of Public Safety because police did not follow-up on the investigation after the legislative session ended.
But Brewer has steadfastly denied that she asked for or received any special treatment.
"Bottom line was indeed I never claimed that I was a state senator nor did I - or do I - believe that elected officials should have legislative immunity. So that was not anything that I brought up, and certainly tried to the best of my ability and I think the report will say that I was very cooperative and polite," Brewer told CNN.
Brewer was appointed governor last year when Secretary of Homeland Security Janet Napolitano stepped down to join the Obama Administration. Brewer remains locked in a tight battle with Democratic state Attorney General Terry Goddard.
