SectionsTVFeaturedMore from NBC Follow NBC News WASHINGTON — Miles Taylor, a former Department of Homeland Security chief of staff, said Republicans like him "don't need to be afraid" of President Donald Trump and should vote against him in the general election.In an interview with Noticias Telemundo, Taylor said he regretted not previously denouncing Trump's family separation policy at the border. Instead, Trump has shown that he only wants to drive immigrants out of the country, while also intimidating his critics in the Republican Party, he said.Taylor has created the Republican Political Alliance for Integrity and Reform (REPAIR), in an effort to "repair" a party that, in his view, is divided between those Republicans who disapprove of Trump but remain silent out of fear, the few others who denounce him and those who simply "cover" for Trump.The group already has two high-ranking former Trump administration officials, who for now prefer anonymity, according to Taylor.Regarding Democratic presidential candidate Joe Biden, Taylor said he's "probably the most qualified person to ever run for president of the United States" and while Republicans have repeatedly labeled Biden as a socialist during their national convention this week, "they can tell that Joe Biden's not a socialist."Taylor, who describes himself as a "fiercely ideologicalRepublican," finds it difficult to support Biden, but in his opinion, he is the only one who can "repair the country."“Now that doesn't mean, I agree with his policy positions.
