FREMONT — Congressional candidate J.R. Majewski received more support from the Republican Party’s top brass Wednesday as House Minority Leader Kevin McCarthy visited Ohio to campaign for him and offer strong criticisms of U.S. Rep. Marcy Kaptur, Mr. Majewski’s opponent. Speaking before a tour of the Crown Battery factory, Mr. McCarthy (R., Calif.) touted Mr. Majewski’s experience working in the nuclear energy field. Mr. Majewski’s career background includes serving in the Air Force, working at the Davis-Besse nuclear power plant, and working as an executive for a company specializing in the storage of spent nuclear fuel. “When America is energy independent, the price of energy is lower, so there’s more businesses, more manufacturing. Also, the world is safer,” Mr. McCarthy said. “But an interesting part is [Mr. Majewski’s] understanding of what it takes for the development in this area as well ... he understands all-of-the-above energy, not just nuclear, not just renewables, not just when it comes to coal or comes to oil and gas.” He also said Ms. Kaptur (D., Toledo), who has served the district since 1983, has “fought American energy” and noted her support of Democratic policies that he feels are driving up energy costs and worsening inflation.
