FILE: Enid Greene Mickelsen, Republican National Committeewoman speaks to delegates and others in attendance at the Utah State GOP convention at the Davis County Conference Center in Layton, Utah, Saturday, June 13, 2009.

WASHINGTON — The Republican National Committee has named a former Utah congresswoman to head the party's rules committee at next month's GOP national convention.

Enid Mickelsen's post will be an important one. Some delegates will be trying to persuade the rules committee to change procedures so it's easier to challenge the expected presidential nomination of Donald Trump.

Trump lost badly to Texas Sen. Ted Cruz in presidential caucuses in conservative Utah. The state is also a home of Mitt Romney, the GOP's 2012 presidential nominee and one of Trump's sharpest critics.

Mickelsen served one term in the House in the 1990s, leaving Congress after a financial scandal involving her ex-husband.

She's Utah's committeewoman on the RNC and former chairman of the Utah GOP. She's been an attorney and talk show host.
