Former Secretary of State Hillary Clinton is calling for greater accountability from U.S. leadership while warning that the country is now in a weakened position in its dealings with Iran following the collapse of recent negotiations.

In a media interview Monday, Clinton sharply criticized President Donald J. Trump’s rhetoric and conduct, arguing that presidential words carry significant consequences both domestically and abroad.

She described recent rhetoric from Trump as “disgraceful” and warned it risks undermining U.S. credibility on the world stage.
