Here's a roundup of news trending across the nation and world today.

What to know now:

1. Democratic sit-in: Democratic lawmakers continued an unprecedented protest on the floor of the U.S. House of Representatives early Thursday, despite the fact the House was officially adjourned, sending representatives home until July 5.  A handful of Democrats have remained in the chamber participating in a sit-in over what they say is the lack of movement on gun control measures.  The gun control measures the Democrats are citing were voted down earlier in the week by the Senate. House Speaker Paul Ryan, (R-Wisc.),  tried to call the chamber to order late Wednesday night, but was shouted down by those protesting.

2. Supreme Court rulings: Today could see rulings on some of the eight cases left to be decided by the U.S. Supreme Court this session. The three most high-profile cases being, access to abortion, affirmative action in college admissions and  immigration.

3. Trump on Clinton: Donald Trump called Hillary Clinton a "world-class liar" Wednesday in a blistering speech where he blamed her for a number of foreign policy failures, and suggested she profited financially from her time in public office.  Also in the speech, Trump said in the first 100 days of his administration he would "appoint judges who will uphold the Constitution of the United States," and would change the nation's immigration rules "to give unemployed Americans an opportunity to fill good - really good - paying jobs."

4. UK voting: It's referendum day in the United Kingdom where citizens there will decide whether to remain a member of the European Union, or to leave the organization.  Those in favor of staying say they like the idea of working with other members of the EU and think the trade agreements between the countries are vital. Those wanting to leave say Britain will be better off making her own decisions on trade, travel and immigration.

5. Body recovered: A body has been recovered in an area in the Gulf of Mexico where a father and his three teenage children went missing after letting relatives know their boat was in trouble. The Coast Guard said the body was that of one of the teens. The teenager was wearing a life jacket, authorities said. Personal items believed to have belonged to the family and that were on the missing boat were also found.

And one more

Serious technical problems affecting emails from then-Secretary of State Hillary Clinton caused State Department IT staffers to temporarily disable security features on the government's own systems, according to emails released Wednesday. The emails made available via a court order in a case brought against the State Department by the conservative legal advocacy group Judicial Watch. According to The Associated Press, the emails show that State Department technical staff disabled software on their systems intended to block phishing emails that could infect systems with viruses. They were trying urgently to resolve delivery problems with emails sent from Clinton's private server, the AP reported.
