Miles Taylor, a former senior Trump administration official, endorsed Joe Biden's presidential campaign on Monday, becoming one of the highest-ranking former Trump administration officials to do so.

Iran Press/America: Taylor, who served as chief of staff to Homeland Security Secretary Kirstjen Nielsen, also accused President Donald Trump of repeatedly using his office for political purposes, including directing officials to cut wildfire relief funding to California because voters there overwhelmingly opposed him in 2016.

Taylor, a longtime Republican and political appointee at DHS from 2017 to 2019, endorsed the former vice president in a video produced by the group Republican Voters Against Trump in which he also made several allegations about Trump's conduct. He also wrote an op-ed published in The Washington Post calling the President "dangerous" for America.

"What we saw week in and week out, for me, after two and a half years in that administration, was terrifying. We would go in to try to talk to him about a pressing national security issue -- cyberattack, terrorism threat -- he wasn't interested in those things. To him, they weren't priorities," Taylor says in the video.

"Given what I have experienced in the administration, I have to support Joe Biden for president and even though I am not a Democrat, even though I disagree on key issues, I'm confident that Joe Biden will protect the country and I'm confident that he won't make the same mistakes as this President."

Taylor also said in his Washington Post op-ed that when Trump moved to close a section of the US-Mexico border in March 2019, he told officials that he opted for a section of the California-Mexico border -- rather than Texas or Arizona -- "because it would be better for him politically."

Other former senior Trump administration officials -- including most recently former national security adviser John Bolton -- have also spoken out against Trump, but few have taken the step of publicly endorsing Biden. Anthony Scaramucci, who briefly served as Trump's communications director, has also voiced his support for Biden.
