Trump Staffer Arrested for Battery. Florida authorities charged Corey Lewandowski with assaulting Breitbart reporter Michelle Fields, who has since left the publication. Trump’s spokeswoman, Hope Hicks, said Lewandowski was “absolutely innocent of this charge,” but according to Detective Marc Bujnowski, surveillance video released from Trump’s Mar a Lago resort “parallels” what Fields told him.

Scott Walker Endorses Cruz. The Wisconsin governor and former presidential hopeful threw his support behind Ted Cruz, calling Cruz a “principled conservative” who is “the best positioned by far” to take down Donald Trump and beat Hillary Clinton in the general election. The endorsement comes ahead of Wisconsin’s primary on April 5. (David M Jackson and Donovan Slack, USA Today)

A Victory for Public-Sector Unions. The eight-justice Court reached a split decision on Friedrichs v. CTA, a case challenging the ability of public-sector unions to collect “agency fees” from nonmembers who benefit from their collective bargaining. Striking down the agency fees would have dealt a major blow to public-sector unions across the country, but the 4-4 split leaves a lower court ruling upholding the fees intact.

Fighting Addiction. The Obama administration introduced new initiatives to fight prescription drug and heroin abuse, including efforts to increase mental health coverage and expand access for addiction treatment. Medicine-assisted treatment “is more effective at sustaining recovery and preventing overdose," Director of the White House Office of National Drug Control Policy Michael Botticelli told reporters. President Obama met with recovering addicts and their families and spoke on a panel at the National Rx Drug Abuse & Heroin Summit in Atlanta. (Nadia Kounang, CNN)

“Without Scalia’s vote, the challenge failed and the lower court’s ruling (calling the challenge “insubstantial”) is affirmed in a one-sentence order. That opinion has no precedential force. But precedent seems not to matter to conservatives in this area. Nor, for that matter, does simple shame, or even a desire to appear non-partisan.” The Atlantic’s Garrett Epps on today’s Supreme Court decision involving public-sector unions.
