A website introducing businessman Daniel McCarthy to Arizona voters popped up briefly Wednesday as he continues to weigh a possible challenge to Sen. Martha McSally for the Republican nomination in 2020.

Around 1:30 p.m. on Wednesday, the website demanddaniel.com displayed more than a dozen photos of McCarthy with his family and political figures, including with President Donald Trump during his 2016 campaign. Soon after, the website contained only text of his biography.

The Arizona Republic obtained images of the website.

"Please note that DemandDaniel.com is strictly a Biography webpage about Daniel McCarthy," the website said. "Daniel McCarthy is conducting due diligence on a campaign currently and is not a committed candidate for any office."

The site provided a form for visitors to fill out if they wanted to encourage him to run for office, or share concerns or comments.

Last week, McCarthy, who lives in Glendale, said he was planning to go to Washington, D.C., and "getting a lay of the land." He said he seriously was considering a Senate run, but declined to elaborate. He has not filed any paperwork with the Federal Election Commission.

The opening page of the website featured a photo of him in front of an American flag and described him as a "God-fearing" husband and father who is an "authentic leader."

McCarthy is a political unknown, although he has been involved in party politics in his legislative district for years. He is the founder of the Phoenix-based Makeup Eraser company.

McCarthy told The Republic Wednesday that versions of his website are being worked on and that demanddaniel.com accidentally went live. He reiterated that he is continuing to explore a potential run for Senate in 2020.

McSally, who is endorsed by Trump and has the support of the Republican Party behind her, is hoping to avoid a primary contest in the upcoming special election. The election will fill the seat once held by the late Sen. John McCain, R-Ariz.

Democrat Mark Kelly, a retired astronaut, Navy pilot and gun-control activist, is seeking his party's nomination. He has not drawn a competitor in the Democratic primary.
