William 'Brute' Bradford runs the DOE's Office of Indian Energy, but his social media past is coming back to haunt him

An appointee to a key position in the Department of Energy apologized on Thursday for a history of incendiary remarks on Twitter – including calling former president Barack Obama a 'Kenyan creampuff.'

William 'Brute' Bradford runs the DOE's Office of Indian Energy, but his social media past is coming back to haunt him.

Bradford's other targets included Facebook co-founder Mark Zuckerberg, whom he called a 'self-hating Jew,' and NBC host Megyn Kelly – whom he referred to as '“MegOBgyn Kelly' as a slam on her feminist advocacy.

The Washington Post exposed the sensational messages, posted to his since-deleted Twitter account.

Bradford's controversial tweets all came before he joined the Trump administration, but they will still give the White House a new headache at a time when it is slowly filling hundreds of key administration vacancies.

'As a minority and member of the Jewish faith, I sincerely apologize for my disrespectful and offensive comments,' he told the Post.

'These comments are inexcusable and I do not stand by them. Now, as a public servant, I hold myself to a higher standard, and I will work every day to better the lives of all Americans.'

Bradford called former president Barack Obama a 'Kenyan creampuff,' a not-so-subtle birtherist dig

The Trump administration appointee called then-president Obama an Iranian stooge and suggested he might have to be forced out of the White House when his term expired

Bradford's comment about Obama came in December, and included an accusation that the former president 'was given his mission in Tehran [a] long time ago, and it suits him just fine.'

'How else can a Kenyan creampuff get ahead?' he asked.

Bradford also tweeted the suggestion that Americans might have to stagte a coup to remove Obama from office if he refused to vacate the White House at the end of his term.

'If Obama won't leave office in January 2017, what will we do? Is a military coup the only answer? Need to think NOW,' he wrote.

That tweet linked to an essay Bradford had written in November 2015 titled: 'Remove Obama: ISIS and the President’s dereliction of duty.'

Bradford wrote that '[i]t is not hyperbolic to suggest that Obama is the single most important figure in the rise of radical Islam and the spread of the Caliphate since the Prophet Muhammad himself.'

He argued that Obama should be impeached, saying that the then-presidnet would likely not lift a finger if 'one million Americans were immolated in a suitcase nuclear attack on New York City.'

Bradford blasted Facebook's co-founder as a 'self-hating Jew' for his anti-Trupm advocacy

He also mocked then-Fox News host Megyn Kelly as 'MegOBgyn,' a slap at her feminist advocacy

Bradford's digital body-slam of Zuckerberg was no less incendiary, following the Facebook guru's plea for Americans to vote against Donald Trump.

'Who is this little arrogant self-hating Jew to tell anyone for whom to vote?' he tweeted.

He offended Japanese-Americans, too, in a February 2015 tweet celebrating the anniversary of the creation of internment camps for that group's citizens during World War II.

'It was necessary,' Bradford tweeted.

He also referred to Kelly, then of Fox News, as 'MegOBgyn,' claiming that he coined the moniker.

Bradford blasted Obama's Pentagon last year for green-lighting female armed service members to serve in combat roles

And Bradford also weighed in on the trend toward allowing women to serve in U.S. military combat roles, conflating it with the larger issue of women serving in the armed forces.

'Women have no business in combat. Period,' he tweeted.

'Republicans [are] pandering on this issue. Disgusting. I'll shoot anyone who comes for my daughters.'

Bradford is a former faculty member at the U.S. Military Academy, the National Defense University, the Coast Guard Academy and the United Arab Emirates National Defense College.

He holds a Ph.D. in political science from Northwestern University, law degrees from the University of Miami and Harvard University, and an M.B.A. from the University of Florida.
