question: What was the full name of the person who barred the National Guard from from interacting with migrants detained by the Border Patrol?
context: A Boston Globe article attributed Barack Obama's win in the 2008 U.S. Presidential election to a marked reduction over the preceding decades in the percentage of whites in the American electorate, attributing this demographic change to the Immigration Act of 1965. The article quoted Simon Rosenberg, president and founder of the New Democrat Network, as having said that the Act is "the most important piece of legislation that no one's ever heard of," and that it "set America on a very different demographic course than the previous 300 years."Immigrants differ on their political views; however, the Democratic Party is considered to be in a far stronger position among immigrants overall. Research shows that religious affiliation can also significantly impact both their social values and voting patterns of immigrants, as well as the broader American population. Hispanic evangelicals, for example, are more strongly conservative than non-Hispanic evangelicals. This trend is often similar for Hispanics or others strongly identifying with the Catholic Church, a religion that strongly opposes abortion and gay marriage.
  ... a right-wing proposal, which says essentially there is no United States ... you're doing away with the concept of a nation-state.  What right-wing people in this country would love is an open-border policy. Bring in all kinds of people, work for $2 or $3 an hour, that would be great for them. I don't believe in that. I think we have to raise wages in this country, I think we have to do everything we can to create millions of jobs.
  April 2018, Trump calls for National Guard at the border to secure the ongoing attempts at a border wall along the United States-Mexico border. According to the LAtimes, "Defense Secretary James N. Mattis has signed an order to send up to 4,000 National Guard troops to the U.S.-Mexico border but barred them from interacting with migrants detained by the Border Patrol in most circumstances".The caravan of migrants from Central America have reached the United States to seek asylum. The last of the caravan have arrived and are processing as of May 4, 2018. Remarks by Attorney General Sessions have expressed hesitation with asylum seekers. Sessions has stated, "The system is being gamed, there's no doubt about it". This statement implied asylum seekers were attempting to immigrate to the United States for work or various other reasons rather than seeking refuge.
