In this Feb. 27, 2017, photo, White House press secretary Sean Spicer speaks during a daily press briefing at the White House in Washington. When Spicer wanted to crack down on leaks last week, he collected his aides’ cell phones to check for communication with reporters. The crackdown quickly leaked. Spicer’s losing round in Washington’s perpetual game of information Whack-a-mole was hardly a surprise. In trying to plug leaks from anonymous sources, President Donald Trump and his aides are going after one of the most entrenched practices in Washington politics and journalism, an exercise that has exposed corruption, fueled scandals and spread gossip for decades.
