Last week, Time Magazine released vintage photos of President Obama at his Hawaii high school prom. On top of that, Sen. Rand Paul, R-Ky., tweeted a boyhood pic with dad, former Sen. Ron Paul, R-Texas, in which the two sat atop a bicycle. On Memorial Day, it was Rep. Darrell Issa’s turn to show and tell. Tweeting an old Army photo, he wrote, “here’s a throwback photo of me getting promoted from 2nd to 1st lieutenant a few years back,” ending the tweet with “#MemorialDay.”
