Lea Marquez-Peterson's long-rumored campaign for Congress is a go.

Marquez-Peterson announced Thursday she's having a campaign launch party as she prepares to run for the GOP nomination in Congressional District 2. The launch party is at 6 p.m. Dec. 14 at the Viscount Suites Hotel.

Marquez-Peterson is the president and CEO of the Tucson Hispanic Chamber of Commerce. After the current holder of that seat, Republican Rep. Martha McSally, began considering a run for U.S. Senate, local GOP bigwigs such as auto dealer Jim Click encouraged Marquez-Peterson to run.

Now, it appears, she's in. And if she's in, apparently McSally is out, although she has not made it official yet.
