WASHINGTON (AP) — Homeland Security Secretary Kirstjen Nielsen is pushing back against a report that she told colleagues she was close to resigning Wednesday after President Donald Trump scolded her at a cabinet meeting. 
  
 Nielsen says in a statement that Trump "is rightly frustrated" that his administration has been prevented "from fully securing the border and protecting the American people." 
  
 She says she shares Trump's frustration. 
  
 The New York Times reported Thursday that the president has growing increasingly angry with Nielsen over what he feels is the country's inability to adequately secure its border. 
  
 The Times reported that Nielsen had drafted a resignation letter but not submitted it. 
  
 Homeland Security spokesman Tyler Houlton says on Twitter that the report is not accurate and Nielsen was not close to resigning. ||||| One person familiar with Mr. Trump’s blowup at the meeting said it was prompted by a discussion about why Mexico was not doing more to prevent illegal border crossings into the United States. Another person said the president was primarily focused on the Homeland Security Department because he viewed Ms. Nielsen as primarily responsible for keeping illegal immigrants out of the country. 
  
 During the meeting, Mr. Trump yelled about the United States’ porous border and said more needed to be done to fix it. When members of his cabinet pointed out that the country relies on day laborers who cross the border each day, Mr. Trump said that was fine, but continued to complain, one person said. 
  
 The president also complained about the continued failure of his administration to find a way to build a wall along the southern border with Mexico, two people familiar with the episode said. 
  
 Ms. Nielsen viewed the president’s rant as directed mostly at her, and she told associates after the meeting that she should not continue in the job if he did not view her as effective. One person close to Ms. Nielsen said she was miserable in her job. 
  
 Mr. Trump has clashed with Ms. Nielsen for weeks about his belief that more should be done to secure the border. In early April, the president repeatedly expressed frustration with Ms. Nielsen that her department was not doing enough to close loopholes that were allowing illegal immigrants into the country, according to one official familiar with those discussions. 
  
 During those discussions, officials had presented Mr. Trump with a list of proposals that would help border agents crack down on those trying to cross the border illegally and send them back more quickly. The president urged Ms. Nielsen to be more aggressive, the official said. 
  
 One persistent issue has been Mr. Trump’s belief that Ms. Nielsen and other officials in the department were resisting his direction that parents be separated from their children when families cross illegally into the United States, several officials said. The president and his aides in the White House had been pushing a family separation policy for weeks as a way of deterring families from trying to cross the border illegally. ||||| The @ nytimes article alleging that the Secretary drafted a resignation letter yesterday and was close to resigning is false. The Secretary is hard at work today on the President's security-focused agenda and supporting the men and women of @ DHSgov. |||||

Homeland Security Secretary Kirstjen Nielsen is pushing back against a report that she told colleagues she was close to resigning after President Donald Trump scolded her at a Wednesday cabinet meeting, the AP reports. Nielsen says in a statement that Trump "is rightly frustrated" that his administration has been prevented "from fully securing the border and protecting the American people." She says she shares Trump's frustration. The New York Times reports that the president has grown increasingly angry with Nielsen over what he feels is the country's inability to adequately secure its border. Trump told reporters before the Wednesday meeting about his frustration with immigration, suggesting the anger yet to come. "We’ve very much toughened up the border, but the laws are horrible," he said. "The laws in this country for immigration and illegal immigration are absolutely horrible. And we have to do something about it—not only the wall, which we’re building sections of wall right now." Nielsen later drafted a resignation letter but did not submit it, according to officials who knew about the episode. Homeland Security spokesman Tyler Houlton tweeted that the Times report is "false" and Nielsen was not close to resigning.
