This CNBC article reports on former President Donald Trump's unsuccessful attempt to persuade a group of Republican representatives, known as the "SALT Caucus," to support a proposed tax bill. These representatives, primarily from states with higher state and local taxes, oppose the bill because it does not sufficiently raise the cap on the State and Local Tax (SALT) deduction. Their continued opposition poses a significant challenge to the bill's passage before the upcoming Memorial Day deadline, despite attempts by Republican leadership to increase the proposed deduction cap. The article highlights the political motivations behind the 2017 cap and the current group's insistence on more substantial relief for their constituents.
