Rep. Byron Donalds, a Republican from Florida who is running for governor, has blamed “rampant illegal immigration” during the Biden administration for measles outbreaks. But we found no link to illegal immigration in several recent large outbreaks, and infectious disease experts told us that the main driver of the cases is falling measles vaccination rates in the U.S.

The NRSC’s Weak Ties Between Brown and Deadly Interstate Crash in Ohio
In the Ohio Senate race, a Republican ad blames former Sen. Sherrod Brown for a deadly crash in April on an Ohio interstate in which an immigrant was charged with vehicular homicide.

The Disagreement over Judicial and Administrative Warrants for ICE
One of the sticking points in the standoff between Democrats and Republicans over funding for the Department of Homeland Security has been the Trump administration’s expanded use of administrative warrants to forcibly enter people’s homes to make immigration arrests. Democrats argue the new DHS policy runs afoul of the Constitution and have demanded immigration officers obtain judicial warrants — a higher legal bar that requires a judge’s approval — to forcibly enter a home.
ICE Officers and Bonuses
Q: Is it true that ICE agents are financially rewarded for the number of people taken into custody?
A: The Department of Homeland Security has said there is no such policy, and an immigration think tank told us it is unaware of any payments per arrest. The Wall Street Journal reported that agents “are rewarded for making arrests” but didn’t say how they are rewarded. Immigration and Customs Enforcement quickly scrapped a proposed program to pay bonuses to speed up deportations.
