Also Wednesday afternoon, three labor groups -- the West Virginia AFL-CIO, the American Federation of Teachers-West Virginia and the West Virginia Education Association -- issued a joint statement endorsing Miley for speaker.
In what is believed to be a close race, the commitment of the six-delegate coalition could be critical.
With 54 Democrats in the House, 28 votes are needed to win the majority party caucus, although it is uncertain whether a replacement for Thompson will be appointed prior to the brief special session of the House of Delegates to elect a new speaker.
Traditionally, the individual that wins the Democratic caucus is supported by all Democrats in the floor vote in the House, making the official vote to elect a speaker a formality.
Staggers said she's hopeful the House will unite behind the new speaker.
"I wish a big hand could come down from heaven and anoint one of them," she said.
Neither Miley nor White could be reached for comment Wednesday.
