Fresh off his win in New York, Republican front-runner Donald Trump insists he can be “presidential” and is confident he will have the 1,237 delegates needed to avoid a contested convention in July. Meanwhile, the RNC is preparing for all scenarios. In the Democratic race, Bernie Sanders continues his insurgent campaign against Hillary Clinton who holds a considerable lead in the delegate count. And President Obama traveled to Saudi Arabia and the U.K. to mend fences with U.S. allies. Obama waded into the British debate about whether to leave the European Union. Plus, Treasury Secretary Jack Lew announced major changes to U.S. currency that will see Harriet Tubman bump Andrew Jackson from the $20 bill. She’ll be the first woman on paper money in more than 100 years.
