MANCHESTER, N.H. (AP) — Newt Gingrich isn't holding back in his criticism of the Cabinet secretary and others behind the troubled rollout of the health care law.

The former House speaker and Republican presidential candidate says Health and Human Services Secretary Kathleen Sebelius (seh-BEEL'-yuhs) and other Democrats are "nut-cake ideologues" and less than competent.

Gingrich is among the prominent Republicans appearing at a gathering of conservatives in New Hampshire on Saturday.

Gingrich and other speakers attacked the health law — and a central piece of the GOP's strategy heading into the fall elections.

Sebelius just announced that she's leaving the Obama administration.

The White House says 7.5 million people signed up for coverage under the health overhaul despite the glitches.
