MIKE PENCE ARRIVES IN SOUTH KOREA, ATTENDS WREATH-LAYING CEREMONY AND EASTER SUNDAY SERVICES. Vice President Mike Pence arrived in South Korea Sunday morning, landing at the U.S. Air Force's Osan Air Base just hours after North Korea's failed missile launch. Pence's 10-day trip to the region also includes stops in Japan, Indonesia and Australia, with a stop in Hawaii on his return to the U.S. The trip follows the North's failed missile test, which was timed to the birth anniversary of the country's late founder and Saturday's military parade in its capital, Pyongyang. A U.S. aircraft supercarrier is also en route to the Korean Peninsula, reports ABC's DAVID CAPLAN. http://abcn.ws/2oAitW1

BIGGEST CONCERN IS THAT KIM JONG UN WILL 'MISCALCULATE,' US MILITARY OFFICIAL SAYS. A top-ranking U.S. military official on the Korean peninsula said the biggest concern is that North Korean leader Kim Jong Un will "miscalculate" his chances of winning any military fight against the U.S. and its ally, South Korea, write ABC's MOLLY NAGLE and NICKI ROSSOLL. “Our biggest concern is that he's going to miscalculate. That's always our concern,” Lt. Gen. Thomas W. Bergeson, the number two U.S. military officer in South Korea said on "This Week" Sunday. http://abcn.ws/2oMMfbY

TRUMP RESPONDS TO PROTESTS DEMANDING HE RELEASE HIS TAX RETURNS: 'THE ELECTION IS OVER.' President Trump apparently remains defiant in response to calls that he release his tax returns, a demand made loudly and visibly this past weekend by thousands of protesters around the U.S. The president took to Twitter on Sunday to deride the Saturday protests as "small," and to suggest that the issue is irrelevant considering his victory in the presidential race. The president also suggested that the protests were organized by "paid" protesters, citing no evidence, notes ABC's ALEXANDER MALLIN. http://abcn.ws/2oDCv3d
