(Ms. Whitmer, a co-chair of the Harris campaign who is also often mentioned as a vice-presidential contender, has said she has no plans to leave her current job.) Mr. Vance will hold rallies on Tuesday in Henderson and Reno in Nevada, and on Wednesday in Glendale, Ariz. Thus far, Mr. Vance, who has had a rocky start, has mostly appeared on familiar Midwestern ground, including in his Ohio hometown, Middletown. Ms. Harris and Donald J. Trump are also on the road this week. Mr. Trump has said he intends to hold another rally in Butler, where the attempt on his life took place, but has not said when.
