The data for this claim is incomplete. Crime figures are low in Florida, but DeSantis’ figure comes from a database containing information from law enforcement agencies that represent only around 57 percent of the state’s population, a Sept. 20 NBC News report found.

The patchy data is related to Florida’s transition to incident-based crime reporting, the new federal standard, rather than the summary-based reports it has used since the 1970s. With summary reporting, if one incident resulted in multiple crimes, only the most serious would be reported. In 2021, the federal government stopped accepting this type of data, and now requires states to report each crime.

FBI’s crime reporting database doesn’t support DeSantis’ figure either. Only 48 out of 757 Florida law enforcement agencies participated in the FBI’s data collection in 2021. The numbers appear to be similar for 2022, according to a Marshall Project analysis.

Haley was just asked about hiring more police officers. According to a May poll conducted by Ipsos for Reuters, 91 percent of Republicans said they were more likely to support a presidential candidate in 2024 who “supports increasing police funding to fight crime.” 53 percent said they were much more likely, while 38 percent said they were somewhat more likely. Just 9 percent said they were less likely to vote for such a candidate.

This is False.

Pence has used this 90 percent drop statistic many times, but has never explained where it comes from.

When the COVID-19 pandemic started, immigration drastically dropped worldwide as governments enacted policies limiting people’s movement. In the U.S., Trump instituted Title 42, a public health policy that authorized the Border Patrol to immediately return most immigrants back to Mexico. The increased use of this policy decreased the use of other programs, including "Remain in Mexico."

U.S. Customs and Border Protection during the pandemic also adopted a new way of reporting migrant encounters. Before the pandemic, it only reported enforcement actions under immigration law; its data during the pandemic includes actions taken under both immigration law and the public health policy. Therefore, 2020 data isn’t entirely comparable to pre-pandemic numbers.

Accounting for challenges in data comparisons, our review found an increase of 300 percent in illegal immigration from Trump’s first full month in office, February 2017, to his last full month, December 2020.

One way to get close to Pence’s alleged 90 percent decrease in illegal immigration is by comparing data from May 2019, the month during the administration that had the highest apprehensions, to April 2020, the month with the lowest enforcement actions in calendar year 2020.

But that’s a severely cherry-picked time period.

Outside of the Trump-critical wing of the Republican primary — featuring Christie and Hutchinson, with major appearances by Pence — most of the presidential field has tip-toed around Trump, careful not to attract his ire. But in the last couple weeks, some candidates have started taking on Trump more directly, jeopardizing their prospects as his running mate.

Trump was already unlikely to name a challenger as his VP pick. Of the 19 unique Democratic and Republican presidential nominees since 1972, only four selected a running mate who had run against them in the same year’s primary. And Trump is even more prickly about loyalty than his recent predecessors.

Last week, we analyzed the tweets of the six highest-polling Republican candidates (other than Trump) in 538’s national polling average. Until recently, DeSantis had hardly acknowledged the former president, mentioning Trump just once since Jan. 6, 2021. But that changed last week, when DeSantis published three critical tweets about Trump. Scott, meanwhile, has largely kept his social media tone neutral toward Trump, but we did see a rare direct criticism on the stump last week, when he said Trump’s suggestion that he’d seek a compromise on federal abortion legislation was the wrong approach. Haley’s tone toward Trump shifted earlier this summer, from cautious to directly critical.

Tonight could tell us whether these recent instances of criticism are the beginnings of a new trend in which the GOP field actually tries to topple the front-runner.
