GRAND RAPIDS, MI — Liz Cheney, daughter of former Vice President Dick Cheney, has cancelled an appearance in Grand Rapids scheduled Tuesday to campaign for Republican presidential candidate Mitt Romney.

A last minute “scheduling conflict” caused Cheney to cancel, said representatives of the Romney campaign in Michigan.

Cheney was planning to appear for guests at a "Women for Mitt" rally beginning at 10:30 a.m. Tuesday at Frederik Meijer Gardens.

The event may be rescheduled with another speaker, says the campaign. It's not clear the nature of the scheduling conflict.

Cheney blasted the Democratic Party claims that Republicans are waging 'war on women' in August.
