The president has called the influx of Central Americans a "national emergency," stoking fears ahead of November's midterm elections.
Fifty years ago, four words broadcast nationally changed the course of the Vietnam War. Now four words have exposed the cruelty of the Trump administration.
An audio file reportedly recorded at a U.S. immigration facility takes center stage in the uproar over the Trump administration's policy of separating immigrant children from their parents.
The Department of Health and Human Services is surveying military sites to house children who are separated from their parents at the border or who arrive unaccompanied by an adult.
Gov. Jerry Brown cites the "criminal threats" of smugglers. He also issues a document emphasizing the National Guard's limited role at the border and explicitly rejecting any guard involvement in immigration enforcement.
Arizona, New Mexico and Texas pledge 1,600 National Guard members to support Donald Trump's plan to use the military to fight illegal immigration and drug trafficking.
Now, as compared with the last two times that troops were deployed to the border, there are far fewer illegal crossings and more Central Americans than Mexicans attempting them.
The announcement comes after the president pledges "strong action today" on immigration and a day after he proposed using the military to secure the southern border until his border wall was erected.
Until the border wall is built, "We're going to be guarding the border with the military," the president says.
