Senator Amanda Chase (R-Chesterfield) will not be a part of the Republican Senate caucus in the General Assembly in Richmond because she objects to the chosen caucus leader, Tommy Norment (R-James City).
From the Richmond Times-Dispatch:
In an interview, Chase said that under Norment’s leadership, the caucus has failed to live up to the “Republican Creed.” Chase said she didn’t challenge Norment for caucus leader, but hoped that other senior senators to the right of Norment would.
“Under Senator Norment, we’ve expanded Medicaid, raised taxes — that’s not Republican” Chase said. “These are outside of what the GOP stands for.”
In September Senator Chase was expelled from her local Republican committee. That story here and here.
