Inevitably, with the Hillary Clinton email scandal snowballing, comparisons are being drawn to Watergate. One of the most memorable jibes came from National Review columnist Jonah Goldberg. He said Clinton's paranoid and calculating way of handling the controversy makes her look like "Nixon in a pantsuit."

More echoes of Watergate: "What did he know and when did he know it?" President Obama told CBS he learned about Clinton's private email system from news reports. But then White House spokesman Josh Earnest said Obama actually did know Clinton didn't use a government email address when she was secretary of state.

Democratic pollster Pat Caddell blasted the Obama administration following a leak that federal corruption charges may be filed against Sen. Bob Menendez, D-N.J., an administration critic. "This White House is Nixon on steroids," Caddell said.
