10 things you need to know today: April 21, 2016

Ted Cruz, wanting to improve upon his dead last finish in New York's Republican primary on Tuesday, is calling for another debate before next week's primaries in Pennsylvania, Connecticut, Delaware, Maryland, and Rhode Island. "Donald [Trump] concluded the people of New York didn't deserve a debate," Cruz told reporters Wednesday in Florida. "Well, you know what? I think the people of Pennsylvania deserve a debate." Since it's now impossible for Cruz to win enough delegates to make him the Republican nominee, his only hope will be to rob Trump of the 1,237 delegates needed to lock the nomination and thus force a contested convention. Cruz will focus on Maryland and Pennsylvania in particular.

Treasury Secretary Jack Lew announced Wednesday that former President Andrew Jackson will soon be replaced by Harriet Tubman on the front of the $20 bill, though Jackson's image will remain on the back. Though the Treasury had initially planned to usurp Alexander Hamilton from his spot on the $10 bill in order to feature a woman on the currency, the Founding Father will also remain on the $10, while leaders of the women's right to vote movement will be featured on Hamilton's flip side. The $5 bill will also be updated to depict civil rights-era leaders.

Former Boston Red Sox pitcher and ESPN baseball analyst Curt Schilling was fired by the network on Wednesday after he shared an anti-transgender meme on Facebook. In a statement, ESPN called Schilling's conduct "unacceptable." The Los Angeles Times reports the meme was a picture of a man in a wig and women's clothing with the caption, "Let him in! to the restroom with your daughter or else you're a narrow minded, judgmental, unloving, racist bigot who needs to die!!!" Schilling is believed to have added the comments, "A man is a man no matter what they call themselves" and "Now you need laws telling us differently? Pathetic."

Up to 500 people are feared dead after a migrant boat shipwrecked off of Libya last week. Survivors say the boat sunk several miles out to sea when smugglers tried to transfer a group of migrants from a small boat onto the larger fishing boat. Forty-one survivors who were still on the small boat when the larger boat sank reported the event to the UNHCR. The shipwreck would be the most fatal in the Mediterranean in many months and brings the sea's total number of mortalities in 2016 to over 1,000, which is more than a quarter of last year's record.

"I believe that if we respect one another's perspectives and seek common ground, we can achieve our shared objective: protecting our citizens," Philpott said. "Better yet, we can improve their lives."

The deal affects diesel versions of the Jetta sedan, the Golf compact, and the Audi A3; larger 3.0-liter diesel vehicles like Audi and Porche SUV models are not part of the buyback deal.
