Back in the United States, the Bush administration’s ongoing effort to win Senate approval of UN Ambassador John Bolton is again facing internal Republican opposition. On Thursday, Republican Senator Lincoln Chafee of Rhode Island said he will not vote for Bolton until the Bush administration answers his questions on US policies in the Middle East. Chafee says he wants the Bush administration to block Israel’s expansion of its settlements in the Occupied West Bank. Senator Chafee is facing re-election this year. Bolton was given a recess appointment last year after his nomination failed to win enough support in the Senate.
