俄克拉荷马州共和党议员马克韦恩·穆林周二宣誓就任美国第九任国土安全部部长，总统唐纳德·特朗普出席了仪式。
48岁的穆林曾是综合格斗冠军和水管生意老板，他将接替即将卸任的部长克里斯蒂·诺姆。诺姆是南达科他州共和党人，最近被特朗普任命领导本月早些时候宣布的“美洲盾牌”安全倡议。
穆林接管国土安全部之际，该机构正面临日益严重的动荡和国会审查。民主党人继续扣留对运输安全管理局（TSA）和其他下属机构的资金，希望迫使美国移民海关执法局（ICE）和美国海关与边境保护局（CBP）改变移民执法行动。
司法部长帕姆·邦迪主持了穆林的宣誓仪式，特朗普称这位俄克拉荷马人“将为国家做出非凡的工作”。

“我告诉你们，你们的家人一定会非常自豪。你们必须非常自豪。每个人都想要这个职位。我说，只有一个人能胜任这个职位，我毫不怀疑他会非常出色，”特朗普说。
邦迪主持完宣誓仪式后，穆林走上讲台，称这是他经历过的最紧张的时刻。
“在椭圆形办公室里，美国总统如此高度评价我，还能叫出我家人的名字并认可他们，这感觉太不真实了。这让我感到谦卑，”他说。
“而且，我从未想当然地认为……但我非常清楚，我不在乎你的州是什么颜色，不管你是红州还是蓝州。归根结底，我的工作是担任国土安全部部长，平等保护每一个人。我们会做到的。我将每天为之奋斗。”
穆林表示，在宣誓就职前，他拜访了国土安全部员工，其中一些人因民主党强制的部分停摆而无薪工作。
“如果你需要知道他们对保护我们享受的祖国和自由的奉献精神，他们为了政治斗争而无偿工作。这就是我需要了解的全部。我告诉……我将365天与你们并肩作战。没人能比我更努力。我也不会让任何人比我更努力。总统把这个重任托付给我，失败是不可能的。”
在与参议院国土安全委员会主席、肯塔基州共和党人兰德·保罗就穆林对一起事件的回应产生争执后，他勉强通过了提名程序。当时保罗的邻居在院子里突然袭击了他，导致他肋骨骨折。
在保罗投下反对票后，穆林需要一名民主党盟友来推动提名通过委员会。宾夕法尼亚州参议员约翰·费特曼（曾作为副州长与社会主义者伯尼·桑德斯有过合作）成为了政治上的特立独行者，并提供了必要的票数，将提名提交给参议院全体会议进行表决。
在那里，他获得了另一位民主党人的支持——新墨西哥州参议员马丁·海因里希。海因里希在一份声明中表示，他不认为穆林会“被胁迫”或“接受白宫斯蒂芬·米勒的指令”。
“这可能会让一些人感到惊讶，但我视马克韦恩·穆林为朋友。我们有着非常坦诚和建设性的合作关系。我们共同起草了《部落水牛管理法案》，今年还一起制定了立法部门拨款法案，”海因里希说。
“我们经常有分歧，但当我们有分歧时，我们会努力找到共同立场。”
作为回应，俄克拉荷马州州长凯文·斯蒂特被任命为穆林的继任者，这一任命受俄克拉荷马州一项特殊法律的约束，该法律要求被提名人承诺不会在11月竞选参议院完整任期。
白宫称“无人”因天使母亲向穆林的呼吁而改变特朗普的执法议程
斯蒂特任命天然气大亨艾伦·阿姆斯特朗为继任者，威廉姆斯公司首席执行官阿姆斯特朗的提名受到一些右翼人士的批评，因为他过去曾向特朗普的批评者、前共和党议员亚当·金辛格捐款。
“他是一位强大的商业领袖，理解自由市场和有限政府的力量。他毕生致力于推动俄克拉荷马州的能源产业，并为全美国提供负担得起的可靠能源，”斯蒂特周二评价阿姆斯特朗时说道。
穆林接替了诺姆，而诺姆之前接替了备受争议的前部长亚历杭德罗·马约卡斯，特朗普曾指责马约卡斯应对边境危机不力。

其他担任过该职位的知名人士包括其首任部长、前宾夕法尼亚州州长汤姆·里奇，他由乔治·W·布什总统在“9·11”事件后提名。里奇后来与主流“MAGA”共和党决裂，转而支持特朗普。
前亚利桑那州州长珍妮特·纳波利塔诺、前空军总法律顾问杰伊·约翰逊、退役将军约翰·凯利以及前特朗普白宫办公厅副主任克里斯蒂·尼尔森也都曾在此职位上留下显著影响。

Sen. Markwayne Mullin sworn in as new DHS secretary, replacing Noem | Fox News

Sen. Markwayne Mullin, R-Okla., was sworn in as the U.S.’ ninth secretary of Homeland Security on Tuesday, with President Donald Trump in attendance.
Mullin, 48, is a former mixed martial arts champion and plumbing business owner who will replace outgoing Secretary Kristi Noem, a South Dakota Republican recently picked to lead the Shield of the Americas security initiative announced by Trump earlier this month.
Mullin will take the reins of DHS at a time of increased turmoil and congressional scrutiny at the agency, where Democrats continue to withhold funding for TSA and other subagencies in hopes of forcing changes to immigration enforcement operations at ICE and CBP.
Mullin was sworn in by Attorney General Pam Bondi as Trump introduced the Oklahoman as a “man who’s going to do a phenomenal job for a country.”

“I tell you, your family has to be very proud. You have to be very proud. Everybody wanted this job. I said, there’s one man for this job and I have no doubt he’s going to be fantastic,” Trump said.
After Bondi administered his oath, Mullin approached the microphone and said it was the most nervous he’s ever been.
“It just seems surreal being in the Oval Office and having the president of the United States speak so highly of me and then recognize my family and know my family by name. It’s humbling,” he said.
“And, I never take it for granted — but I’ve made this very clear that I don’t care what color your state is. I don’t care if you’re red or you’re blue. At the end of the day, my job is to be secretary of Homeland [Security] and to protect everybody the same. And we will do that. I’ll fight every single day.”
Mullin said that prior to his swearing-in, he visited with DHS employees including some working without pay due to a Democrat-forced partial shutdown of the agency.
“If you need anything to know their dedication to show up and still protect the homeland that you and I enjoy and the freedoms that we’re that we’re experiencing, they’re working with for free because of political politics. That’s all I need to know. I told … I’ll be fighting 365 days beside you. No one’s going to outwork me. And I’m not going to let any of them outwork me. The president is entrusting me with this, and failure’s not an option.”

He narrowly made it through the nomination process after clashing with Senate Homeland Security Committee Chairman Rand Paul, R-Ky., as the two continue to feud over Mullin’s response to an incident in which Paul’s neighbor blindsided him in his yard, fracturing his ribs.
Mullin needed a Democratic ally to get his nomination out of committee after Paul’s no vote. Sen. John Fetterman, D-Pa., who formerly exchanged endorsements with socialist Sen. Bernie Sanders, I-Vt., as Pennsylvania’s lieutenant governor, has become somewhat of a political maverick and provided the necessary vote to advance the nomination to the full Senate.
There, he garnered support from another Democrat, New Mexico Sen. Martin Heinrich, who said in a statement that he doesn’t believe Mullin will be “bullied” or allow himself to “take orders from Stephen Miller” at the White House.
“This is going to surprise some people, but I consider Markwayne Mullin a friend. We have a very honest and constructive working relationship. We have authored legislation together, such as the Tribal Buffalo Management Act, and we crafted the Legislative Branch Appropriations bill together this year,” Heinrich said.

“We often disagree and when we do, we work to find whatever common ground we share.”
In turn, Oklahoma Gov. Kevin Stitt was tasked with naming Mullin’s replacement, which was subject to a unique Sooner State law that requires the nominee to pledge not to run for a full term in the Senate come November.

Stitt named natgas magnate Alan Armstrong, chief executive of the Williams Companies, whose nomination was criticized by some on the right given the mogul’s past donations to then-Rep. Adam Kinzinger, R-Ill., a vocal Trump critic.
“He’s a strong business leader who understands the power of free markets and limited government. He spent his career fighting for Oklahoma’s energy industry and providing affordable, reliable energy to all of America,” Stitt said of Armstrong on Tuesday.
Mullin succeeds Noem, who herself succeeded controversial Secretary Alejandro Mayorkas, whom Trump blamed for the open border crisis.

Other top names who have held the role include its inaugural secretary, former Pennsylvania Gov. Tom Ridge, nominated by President George W. Bush in the wake of 9/11. Ridge has since broken with the mainstream “MAGA” GOP in his support for Trump.
Former Arizona Gov. Janet Napolitano, former Air Force general counsel Jeh Johnson, Gen. John Kelly (Ret.), and former Deputy Trump White House chief of staff Kirstjen Nielsen also prominently served.
