The claim states Mace argued the evidence is 'overwhelming' while the Ethics Committee hasn't released findings. While the web search results confirm Mace made strong accusations (Claim 3), the evidence provided does not contain a direct quote or report confirming Mace specifically stated the evidence was 'overwhelming' *while* noting the committee had not released findings. The evidence is insufficient to corroborate this specific framing across multiple sources.

The concept that an expulsion resolution requires a supermajority vote (two-thirds) is a standard procedural fact, but the provided evidence only contains general definitions of 'expulsion' from dictionary sources and does not cite the specific House rule requiring two-thirds support. Therefore, while the claim is likely true based on external knowledge, the evidence provided is insufficient to verify the specific procedural requirement from a reliable source.
