Former Fox News host Kimberly Guilfoyle on Monday rallied Catholics to support President Trump, citing his commitment to anti-abortion and religious liberty causes as the “single issue” that should drive their votes.

Guilfoyle, one of Trump’s top fundraisers and Donald Trump Jr.’s girlfriend, in the past week emerged as one of the campaign’s most vocal ambassadors to the religious voters. Touting her Catholic upbringing and education as bona fides, the controversial media personality has positioned herself as a critic of abortion, and “liberal politicians trying to shut down churches and other houses of worship across the country by giving free to the rioters and looters in the streets.”
