evidence: Public county data doesn’t separate case numbers by city or demographics, so public health experts cautioned against tying changes in case rates to immigrants. When discussing immigrants in the U.S. more broadly, Vance mischaracterized one of Harris’ proposals, saying she "wants to give $25,000 to illegal aliens to buy American homes." But Vance is filling in blanks about a proposal that we know little about. Harris has not detailed her plan or said who would qualify for this first-time homebuyer assistance. Walz’s attacks on Vance and Project 2025 Like Harris, Walz routinely works in warnings about Trump and Vance embracing proposals from Project 2025, even though the Trump-Vance campaign has distanced itself from the 900-page policy manual for the next Republican administration. Walz said Vance "literally wrote the foreword for the architect of the Project 2025 agenda." This is True.
