U.S. Rep. Robert Aderholt of Haleyville, a Republican of Alabama and US Rep Frank Wolf of Virginia (Republican) and US Rep Joseph Pitts of Pennsylvania (Republican). Not a peep was said about that.
And less than 2 days after? Rep. Darrell Issa (California Republican) who actually critized Bush for failing to promote dialog with Syria (something Speaker of the House Pelosi did NOT do).
I short, it is not unusual, unseemly or unpatriotic to visit a foreign leader. Even one the President doesn't like. Even if you are a Democrat or a Woman or just someone that pisses Deadeye Cheney off.
