Via Elizabeth Benjamin, we get this news story on Rep. Charles Rangel demanding Tom Suozzi return campaign contributions from Home Depot bigshot Kenneth Langone - who has been critical of House Democrats:

...Rangel suggests that Suozzi must choose between being a good Democrat or sticking with Langone.

"I respect your role as an outsider. But there is a fine line between being an outsider and turning your back on the Democratic Party and what it stands for."

It's unclear whether Rangel sent similar letters to Democratic colleagues U.S. Sen. Charles Schumer and U.S. Sen. John Kerry who, according to the Center for Responsive Politics, have also accepted campaign contributions from Langone.
