Tyler Clementi Higher Education Anti-Harassment Act of 2025

Maddy summaryThis bill requires U.S. colleges and universities to update their anti-harassment policies to explicitly cover online communications (like emails and social media) and all campus activities, including off-campus events and dormitories. It mandates institutions to create clear procedures for reporting harassment based on protected characteristics (such as race, gender identity, or disability), including how they will investigate and respond to incidents. The bill also creates a new $50 million annual grant program to fund schools developing prevention programs, counseling services, or training for students and staff on recognizing and addressing harassment. These requirements supplement existing federal civil rights laws like Title IX but do not replace them.

A joint resolution proposing an amendment to the Constitution of the United States relating to the authority of Congress and the States to regulate contributions and expenditures intended to affect elections and to enact public financing systems for political campaigns.

Maddy summaryThis proposed constitutional amendment would explicitly authorize Congress and state governments to regulate campaign contributions and spending to influence elections, requiring such regulations to be viewpoint-neutral and reasonable. It would also permit states and Congress to establish public financing systems for campaigns, potentially offsetting private spending with public funds. The amendment allows distinctions between natural persons and corporations (including bans on corporate spending in elections) while explicitly protecting press freedom. As a proposed amendment, it would only take effect if ratified by 38 states within seven years.

Protect America’s Workforce Act

Maddy summaryThe Protect America’s Workforce Act (S 2837) directly affects federal employees and their labor unions by reversing two executive orders that limited their collective bargaining rights. It nullifies Executive Orders 14251 and 14343, which had excluded certain federal workers from labor-management programs, and prohibits federal funding for any efforts to implement those orders. The bill ensures that all existing collective bargaining agreements between federal agencies and employee unions remain fully enforceable through their original terms, as long as they were in effect as of March 26, 2025. This preserves current workplace agreements without creating new obligations or altering existing labor-management processes.

Billionaires Income Tax Act

Maddy summaryThe Billionaires Income Tax Act (S 2845) would require high-net-worth individuals with at least $1 billion in assets or $100 million in annual income (or $500 million/$50 million for married filing separately) to pay taxes annually on investment gains rather than deferring taxes until assets are sold. It implements "mark-to-market" taxation for tradable assets like stocks and closes loopholes that allow tax-free transfers of assets to heirs, eliminating strategies like "buy, borrow, die." The bill targets "applicable taxpayers" by requiring annual tax payments on investment gains and modifies special tax provisions for investments in small business stock and qualified opportunity funds. The law would apply to individuals meeting either the asset or income test for three consecutive years, with specific rules for married couples and trusts.
