Vice presidential candidate and Trump running mate Vance has called on billionaire Peter Thiel to support the Trump campaign. Peter Thiel, the co-founder of PayPal and Palantir, has been reluctant to endorse any candidate in this year's election, despite donating to the Republican campaign in 2016 and sponsoring Vance's 2022 run for U.S. Senate. Frustrated with a Trump presidency last year, Peter Thiel said he did not plan to "give any money to Republican politicians in 2024", adding: "It's always possible for me to change my mind."
