Washington (CNN) -- In the context of 2016, Hillary Clinton and Elizabeth Warren are rivals for the Democrats' presidential nomination whose every word about each other is scrutinized and picked apart. But Warren and Clinton have been on the national stage for years, and before they were ever considered rivals, they met each other in the late '90s. Warren spoke about the meeting in a 2004 interview on Bill Moyers' "NOW on PBS" show. Warren reflects glowingly of Clinton as first lady but also bluntly talks about how Clinton's election to the Senate in 2000 changed the former secretary of state.

The 2004 exchange shows how Warren's changed, too -- she's now less candid about Clinton
@placeholder is not the only one who was changed by the U.S. Senate, however.
