WASHINGTON – The United States has dropped out of the “top 20” in a global-league table of least-corrupt nations, tarnished by financial scandals and the influence of money in politics, Transparency International said yesterday.

Somalia was judged the most corrupt country, followed by Myanmar and Afghanistan (tied second-worst) and then by Iraq, in the Berlin-based watchdog TI’s annual corruption perceptions index (CPI).

The U.S. fell to 22nd from 19th last year, the lowest score awarded to the United States in the index’s 15-year history.
