President Trump’s demand for $5 billion to start a border wall has ground the federal government to a halt for a third week.

In yesterday’s Oval Office address, Trump said one reason the wall was necessary is to stop drug traffic. But IPS Drug Policy Project director Sanho Tree argues that a wall would actually be counterproductive, because the drug trade is heavily incentivized by prohibition policies. (He explained this last year in a New York Times op-ed.)

Tomorrow, Thursday, January 10 at 12:00pm EST, we invite you to join Sanho for a discussion of the wall, its role in the drug war, and the deeply authoritarian politics it plays into.

We’ll broadcast the talk live on the Institute for Policy Studies Facebook page from 12:00-1:00pm EST. Send your questions for Sanho to our Facebook Live post once the event starts, or tweet us at @IPS_DC with hashtag #NoWall.

DC-area residents can join the event in person at the Institute for Policy Studies office.
