The Memo: New Orleans mass killing gets pulled into partisan political battle

It took less than 48 hours for the mass killing in New Orleans to be pulled into the partisan debates that are roiling the nation.

In the process, some of the political rhetoric ran roughshod over the facts.

President-elect Trump, for example, quickly took to social media to imply that lax immigration policies were responsible for the carnage on New Orleans’s Bourbon Street, where a man in a rented truck mowed down revelers at around 3:15 a.m. on Wednesday, killing 14 people.
