Virginia Gov. Bob McDonnell (R), who spent time with Romney in Utah over the weekend, will skip the event. Instead, he will headline a lunchtime fundraiser for Romney in Washington, according to McDonnell’s office. (Romney will not attend.)

Attorney General Ken Cuccinelli (R), who did not endorse a candidate in the presidential primary race, is expected to attend the campaign event in Salem (unless the Supreme Court ruling on health care interferes with that). Lt. Gov. Bill Bolling (R) and U.S. Senate candidate George Allen (R) will not be there.

Bolling will be at a Republican Lieutenant Governor’s Association meeting in Lake Tahoe, his office said.

Allen’s campaign said he has previously scheduled commitments. “He looks forward to campaigning with him in the future,’’ spokeswoman Emily Davis said.

The Romney campaign event was announced by local lawmakers. Campaign officials confirmed the event, but offered no other details.

The noon event will be at Carter Machinery in Salem.

Romney made two campaign stops in Virginia last month -- in Chantilly and Portsmouth. He also spoke at Liberty University’s graduation.
