When news about United States agents separating immigrant children from their parents at the Texas border under the Trump administration’s new zero-tolerance policy on illegal immigration began to circulate widely last week, Willie Nelson spoke up quickly. "What's going on at our Southern border is outrageous," Nelson told Rolling Stone last Thursday.

Now he's taking it a step further. Addressing Trump directly on Twitter on Monday evening, Nelson suggested the two of them visit one of the border detention centers together:

@realDonaldTrump
Hey Donald this is@WillieNelson Let’s go down to a border detention center together to better understand what’s happening down there?!
Let’s talk!@PaulBegala@RepBetoORourke@SenFeinstein@maddow@RepAdamSchiff@tedlieu@SpeakerRyan@SenateMajLdr@maddow

Though the tweet was not posted from Nelson's own account, his publicist, Elaine Schock, verified that it came from Nelson. His @WillieNelson twitter appears in the post, as well as that of @realDonaldTrump. The post was made from the account of @BioAnnie1, which appears to be the Twitter name of Annie Nelson, Willie's wife.

The post also tagged several other prominent legislators on both sides of the aisle, including Texas Rep. Beto O'Rourke and House Speaker Paul Ryan, as well as media figures including Rachel Maddow and Paul Begala.
