Hillary Rodham Clinton is questioning the application of the death penalty, though she says she still supports the measure in certain circumstances.
She says the federal government has to take a "hard look" at the punishment, which she says has been "too frequently applied" and often in an indiscriminant manner.
The leading Democratic primary candidate does not favor abolishing the measure altogether but she says its use should be "very limited and rare."
Clinton is in the midst of a two-day campaign swing through New Hampshire, wooing voters in the early primary state.
