— -- 1. Obama's Message to Graduates Sounds Like Anti-Trump Stump Speech

While not directly naming the candidate, President Obama made it clear just what he thinks about Donald Trump's campaign and policy proposals in a highly political commencement speech Sunday at Rutgers University.

The president said he would skip giving students the usual commencement banter, and instead run down a list of "suggestions" that turned out to be a stern and direct indictment of everything Trump has built his campaign on.

First, Obama took on Trump's "Make America Great Again" campaign slogan, telling students, "When you hear someone longing for the good old days, take it with a grain of salt."

Obama told graduates that despite what they may hear on the campaign trail, he believed they were better positioned than at any time to succeed and said the reason America doesn't tend to move backwards is "because you don't fear the future."

2. Dozens Arrested in 'Break Free' Climate Change Protests Across the US

At least 57 climate change activists were arrested Sunday in conjunction with the so-called "Break Free" protests against the use of fossil fuel.

The bulk of the arrests took place in Washington state this morning, when 52 activists were cited for trespassing on railroad tracks, according to the Skagit County Department of Emergency Management. One person was cited for resisting arrest. The other five arrests took place in Albany on Saturday on similar grounds.

In Washington, approximately 150 people had spent the night camping out on railroad tracks that lead to two refineries, according to a spokesperson for BNSF Railway. The protests were peaceful, according to the spokesperson, and the majority of activists obeyed a request to leave the tracks at 5 a.m. PT today.

The Break Free protests represent part of a "global wave" of action taking place across six continents over 12 days targeting "the world's most dangerous fossil fuels," according to a statement published by the organizers earlier this month.

"2015 was the hottest year ever recorded and the impacts of climate change are already hitting communities around the world. From rising sea levels to extreme storms, the need to act on climate change has never been more urgent. Added to that, the fossil fuel industry faces an unprecedented crisis -- from collapsing prices, massive divestments, a new global climate deal, and an ever-growing movement calling for change. The time has never been better for a just transition to a clean energy system," the group's statement reads.
