Despite the heroism she displayed in becoming the public face of the Trump administration's family separation policy\u2014which she once claimed didn't exist\u2014Kirstjen Nielsen, Department of Homeland Security Secretary, was unceremoniously asked to resign during a meeting with President Trump early Sunday evening. The reasoning, in part,\u00a0was that\u00a0she's reportedly not hardline enough\u00a0for resident White House\u00a0crypt keepers\u00a0Stephen Miller\u00a0and\u00a0John Bolton. Although Nielsen isn't technically leaving her post until Wednesday, here's a look back at some of Nielsen's worst moments as DHS chief anyway. Teargassing migrants\u00a0 Nielsen reportedly endured a rocky relationship with President Trump\u2014she can join the club\u2014especially after\u00a0her closest ally and fellow immigration hawk, former DHS secretary John Kelly, left the department after\u00a0serving\u00a0as Trump's chief of staff. According to the New York Times, Trump frequently "called Ms. Nielsen at home early in the mornings to demand that she take action to stop migrants from entering the country, including doing things that were clearly illegal, such as blocking all migrants from seeking asylum." That's not to say Nielsen didn't enjoy fleeting moments of Trump's approval. The Washington Post reported\u00a0yesterday that one particular "atta girl" moment came when\u00a0Border Patrol officers deployed tear gas\u00a0on Central American migrants attempting to break through a border fence in Tijuana in 2018. Lied about family separation policy\u00a0 In January 2018, Nielsen\u00a0testified before Congress\u00a0that the DHS "did not have a policy of family separation" resulting in thousands of migrant children being\u00a0removed\u00a0from the guardianship of their parents. It was later revealed that she signed off on an internal memo outlining a\u00a0\u201czero tolerance\u201d policy that called for the prosecution of every adult caught crossing the border that would result in children being taken from their parents. \u201cDHS could also permissibly direct the separation of parents or legal guardians and minors held in immigration detention so that the parent or legal guardian can be prosecuted,\u201d the memo read. Didn't know how many people died in DHS custody Following the death of 7-year-old Guatemalan migrant Jaklin Caal Maquin, Nielsen was unable to give a precise figure as to how many migrants seeking asylum have died while in DHS custody when asked by Rep. David Cicilline (D-RI) during a Congressional hearing in December. Rep. Cicilline: You do not know how many people have died in DHS custody? DHS Sec. Nielsen: "I don't have an exact figure" ... Cicilline: "I'm talking about people who have died in your custody. You don't have the number?" Nielsen: "I will get back to you with the number." pic.twitter.com\/SxEmRe4CM2 \u2014 NBC News (@NBCNews) December 20, 2018 Jesus. Blamed migrant\u00a0child's death while in DHS custody on her family. After Maquin passed away from dehydration and exhaustion while in border patrol custody, Nielsen told the empty little mannequins at\u00a0Fox & Friends\u00a0to shift blame over towards her family for trying to provide a better life for their kid by taking her to the United States, despite the fact that the\u00a0Maquin\u00a0reportedly started exhibiting symptoms eight hours after being detained by border patrol agents FOX & FRIENDS: What do you know about the 7-year-old girl who died in Border Patrol custody?@SecNielsen: "This is just a very sad example of the dangers of this journey. This family chose to cross illegally... I cannot stress how dangerous this journey is." pic.twitter.com\/bjFMdFlW3E \u2014 Aaron Rupar (@atrupar) December 14, 2018 Had the audacity to eat at a Mexican restaurant after enacting "zero tolerance" policy against migrants crossing the Southern border. Amid the controversy over border patrol agents putting migrant children apprehended at the Southern border in cages, Nielsen felt entitled to hold a "work dinner" at MXDC Cocina Mexicana, a high end Mexican restaurant in D.C. It didn't take long for at least 15 protestors to show up\u00a0and\u00a0yell at her for having the audacity to dine at a Mexican restaurant. \u201cIf kids don\u2019t eat in peace, you don\u2019t eat in peace,\u201d protestors shouted at Nielsen, according to video footage captured by the Metro D.C. Democratic Socialists of America. Nielsen left shortly after her dinner was interrupted. DHS Secretary Nielsen just got driven out of a Mexican restaurant here on 14th Street by activists.
