Mary Trump shared a video on X about the refugee crisis on the American-Mexico border. She wrote: "Mitt Romney reveals that Donald [Trump] is actively encouraging Republican senators and congressmen to vote against border legislation to make Biden look bad" Immigration is one of the top issues before the presidential election.

Trump, the Republican Party's presumptive presidential nominee, has promised tougher measures, such as launching the largest domestic deportation operation in U.S. history. According to US Customs and Border Protection (CBP), there were more than 2.4 million crossings at the southern border in fiscal year 2023, compared to around 1.7 million in 2021. The bill was rejected by the Senate in February as conservative hardliners argued it did not go far enough to end illegal immigration into the country. All but three Republican senators - including Romney - voted against the bill. In surveys, Americans show doubts about President Joe Biden's border policy. Experts cite other factors, including instability in some Central American countries.
