Hagan, in 140 characters

U.S. Sen. Kay Hagan has launched both a YouTube channel and a Twitter account to chronicle her work in the U.S. Senate.

For now, her last Tweet is from "the office of Sen. Kay Hagan," with updates posted by staff. Example: "welcoming a great group of North Carolinians for this week's Carolina Coffee," Barb Barrett reports.

Hagan had a campaign Twitter account last year, posting about her platform, her daily travels and occasional jabs at the competition ("This is what a Republican-run, special interest-based economy looks like," she tweeted a year ago.)

Her YouTube channel has a pair of videos so far. One welcomes viewers; the other features her biography.

"Tools like YouTube and Twitter will allow me and my office to share information about the most pressing issues facing North Carolina and our country and keep constituents updated about the latest news in the Senate," Hagan said in a statement. "North Carolinians can use these tools to keep up with me while I am in Washington and traveling across the state."
