Politicians have always sworn, but it was not until recently that their blue language has made it into the public record.

White House press secretary Karoline Leavitt made her briefing debut on Tuesday, where she sparred with reporters over a federal freeze on grants and made clear that President Donald Trump himself will be the administration's main messenger.

When Leavitt, 27, walks out into the James S. Brady Press Briefing Room on Tuesday, she'll be the youngest press secretary to do so, since Ronald Ziegler, who held the title in former President Ronald Reagan's White House at age 29.
