WASHINGTON (AP) — The opposition to President Barack Obama’s nominee for U.S. ambassador to Norway is growing in Congress, with a group of House Democrats and Republicans asserting that George Tsunis’ “embarrassing lack of knowledge” about the country makes him unqualified.

In a letter last week and a statement on Friday, lawmakers highlight Tsunis’ comments about Norway at his Senate confirmation hearing in January and called on Obama to withdraw the nomination. The president nominated Tsunis, a New Yorker, Democratic fundraiser and chairman of Chartwell Hotels, to the post.
