USA: Republicans in Washington struggled to fill a leadership void on Thursday as the front-runner to take control of the House of Representatives, Kevin McCarthy, quit the race in a surprise announcement that heightened concerns about the party's ability to govern effectively.
Representative McCarthy, the No. 2 House Republican, had been expected to win Thursday's contest for the nomination to succeed retiring Speaker John Boehner despite opposition from more conservative lawmakers demanding a harder line against Democratic President Barack Obama's agenda.
