Mark Penn, Colombia, and many, many Clinton days off message

Sam Stein at HuffPo looks at Bill Clinton's ties to Colombia and his previous support and connections to the trade deal. (Clinton's strength is that she's been "vetted," right?)

(Politico) The Clinton campaign is still trying to describe how Mark Penn was fired, but not fired.

(Politico) Ben Smith offers two guesses as to why Mark Penn hasn't really been thrown under the bus. "Penn knows everything, and might go on a damaging (on or off-record) media tour if cut loose; and the campaign owes Penn money, and it may be hard to terminate his contract without paying him."

(WSJBlog) Obama Surrogates Attack Clinton Over Penn’s Lobbying

It's not going away yet, is it?

Later:

The presidential campaign of Sen. Hillary Rodham Clinton said Tuesday that her husband, the former president, supports a free trade agreement with Colombia that she strenuously opposes.

Also a similar headline and tone on page 4 of the WSJ.

This just keeps getting messier for Clinton.
