Longtime Republican activist Trixie Averill will be stepping down as state director of Americans for Prosperity, a group that supports a free market, low taxes and transparency in government.

We hear that Averill was asked to leave the job she has held for only a few months, but she tells us she is happy with the change.

She will become the statewide director of grassroots — a new position — after the organization finds a replacement. She said she wants to get back to tasks she enjoys and escape some of the administrative duties.

Averill, the GOP’s former Sixth Congressional District chairwoman who served on its Republican State Central Committee, replaced Ben Marchi, who left the organization after three years.

Gov. Robert F McDonnell (R) has had close ties to Americans for Prosperity over the years. His former campaign manager, Phil Cox, worked for the group and its current president Tim Phillips has advised the governor. But, under Marchi, the AFP chapter in Virginia was sometimes at odds with McDonnell.

Averill is well known — volunteering on campaigns, lobbying for various consulting firms and serving on community boards, including the Virginia Tourism Corporation.

“I’m still very happy with AFP,’’ she said.
