It's White House Science Fair Day

While Republican Senator Ted Cruz launched his presidential campaign on Monday and former Secretary of State Hillary Clinton waded back into policy waters, President Barack Obama was up to something a little less political: the White House science fair. Obama was set to announce $240 million in private-sector pledges for science, technology, engineering, and math education at the event, according to the White House. He told the participants: “Keep explaining. Keep dreaming. Keep asking why.”
