Midday Roundup: Here comes Hillary, but where's she headed next?

On tour. Former Secretary of State Hillary Clinton kicks off a mega book tour today to promote her new memoir Hard Choices. The tour will last several months with stops from Canada to Texas. The pace of the schedule resembles a political campaign, and the tour could turn out to be a run-through for the 2016 presidential race. Though Clinton has not yet thrown her hat in the ring, the tour is sure to keep the “Will she or won’t she?” storyline going strong. Clinton played coy in an ABC News interview that aired Sunday, saying she would decide whether to run “when it feels right for me to decide.”

Vegas shooting. A man and woman went on a shooting rampage then killed themselves in a Las Vegas Walmart on Sunday. The attack began at a CiCi’s Pizza, where the shooters killed police officers Alyn Beck, 41, and Igor Solder, 31. The man and woman fled to a nearby Walmart where they killed a third person. Police say the female suspect shot her male companion before killing herself. During the attack, One of the shooters yelled “This is a revolution!” But police say a motive remains under investigation. A police spokesperson called the investigation complex because it involves more than 1,000 witnesses.

Summer of Shailene. The Fault in Our Stars won big in its opening weekend at the box office. The teen-romance-slash-tearjerker earned nearly double the returns of Tom Cruise’s latest action flick, Edge of Tomorrow, which came in third behind the week-old Maleficent. Though it opened at No. 1, Stars failed to exceed the opening weekend returns of Divergent, another teen favorite that also stars Hollywood’s quirky darling of the moment, Shailene Woodley.

Stage presence. Hugh Jackman hosted last night’s high-energy Tony Awards, where big winners included Bryan Cranston for best actor in a play, Neil Patrick Harris for best actor in a musical, and Audra McDonald, who won best actress in a play, her sixth Tony. McDonald is now the biggest Tony winner of all time. All the Way, a look at Lyndon B. Johnson’s presidency, starring Cranston, won best play, and A Gentleman’s Guide to Love and Murder took best musical.

Sore loser. The horse Tonalist won Saturday’s Belmont Stakes, dashing hopes that California Chrome would win the elusive Triple Crown. But the real newsmaker was California Chrome’s co-owner Steve Coburn, who after the race made a red-faced, on-camera rant against his competitors. Coburn took issue with the fact that many horses in the Belmont Stakes, including Tonalist, had not entered the Kentucky Derby or the Preakness and got a fresh run, unlike California Chrome. But Coburn took it all back Monday morning, apologizing on Good Morning America to Totalist’s owners and to his wife.
