The claim that a senior House Republican warned of an 'explosive' wave of early resignations similar to Marjorie Taylor Greene's, which could cause Republicans to lose their House majority before the midterms, is mostly true because multiple independent sources report such warnings and concerns from GOP insiders, though the exact scale and timing remain uncertain.
A senior House Republican says an "explosive" wave of House Republicans will soon RESIGN early from Congress like Marjorie Taylor Greene did. It would make Republicans lose the majority even before the midterms.

What the Evidence Shows
Multiple reputable sources independently report that a senior House Republican has publicly warned about a potential wave of early resignations among House Republicans following Marjorie Taylor Greene's announced resignation. These reports describe a significant morale crisis within the House GOP, citing dissatisfaction with leadership including Speaker Mike Johnson and former President Trump. Several articles explicitly mention predictions that these resignations could lead to the GOP losing its majority before the 2026 midterm elections. However, while the warnings are consistent across sources, none provide concrete evidence of how many members will resign or confirm that this will definitively cause a loss of majority. Some reports note that other GOP members are considering early retirement or resignation but do not confirm an imminent mass exodus. The timing is also somewhat vague; some sources suggest it could happen before the midterms, but no specific dates or numbers are given.thedailybeast.comthedailybeast.comFurious House Republican Warns More ‘Explosive’ Resignations Are Coming After...

Therefore, the core claim about warnings of an 'explosive' wave of resignations and potential loss of majority is well-supported by multiple independent reports quoting senior Republicans and insiders. Yet, the scale and certainty of this outcome remain speculative at this stage.
