Tenure
Kean is a member of the Republican Main Street Partnership, and joined the Problem Solvers Caucus. Kean said he joined the caucus to assure constituents that he remains committed to "working across the aisle".
Sue Altman, his opponent in the 2024 election, and other critics have called Kean out for not holding in-person town halls. Fred Snowflack of Insider NJ minimized the potential negative impact on Kean, reporting that "Dating back to last fall's campaign, most of those griping about Kean's incommunicado ways were the media and voters who probably were not going to support him anyway."
During his 2022 election campaign, Kean, who self-describes as pro-choice, promised voters that he would support abortion rights. After the Dobbs decision, he said "this decision is now best to happen on the state level." During his tenure, he voted against the Women's Health Protection Act which would have codified the abortion rights that the Supreme Court overturned. He voted for the Born-Alive Abortion Survivors Protection Act, which would penalize healthcare practitioners who fail to provide care for an infant that is born-alive from an abortion attempt. Kean has expressed support for IVF and introduced legislation to provide income tax credits to people undergoing fertility treatments.
On October 5, 2023, Kean signed a letter to the House Agriculture Committee along with 15 House Republicans opposing the inclusion of the Ending Agricultural Trade Suppression (EATS) Act in the 2023 farm bill. The EATS Act, introduced in response to the California farm animal welfare law Proposition 12, would have overturned state and local animal welfare laws restricting the sale of agricultural goods from animals raised in battery cages, gestation crates, and veal crates. The letter argued that the legislation would undermine states' rights and cede control over U.S. agricultural policy to the Chinese-owned pork producer WH Group and its subsidiary Smithfield Foods.
In 2024, Kean, one of 17 House Republicans representing a district that voted for Joe Biden in the 2020 presidential election, endorsed Donald Trump.
In 2026, Kean voted in favor of legislation extending Affordable Care Act premium tax credits, joining 16 other Republicans supporting the bill.
In February 2026, Kean supported Trump's initial strikes in the 2026 Iran war. Kean has voted against multiple resolutions concerning presidential war powers in the context of that war.
