Ensign ethics probe heats up

From NBC's Mark Murray
Here's another reminder, from KLAS-TV in Las Vegas, that the ethics cloud hovering over Sen. John Ensign (R) hasn't gone away.

From the KLAS investigative report:

This week, at least two attorneys for the Senate Ethics Committee were camped out at a hotel near the Strip where they interviewed a string of witnesses whose testimony could mean the end of John Ensign's political career.

What they didn't know is that the I-Team was watching the whole thing go down.

The first familiar face to arrive Monday afternoon at the Marriott Suites was Dan Albregts, attorney for Doug and Cindy Hampton, the husband and wife who worked for Senator Ensign and who were close personal friends with Ensign's family until the senator admitted he'd carried on a long extramarital affair with Mrs. Hampton.
