Ros-Lehtinen said the presence of Venezuelan President Hugo Chavez and Iranian President Mahmoud Ahmadinejad at the inauguration shows that these "brutal leaders" are sticking together.
"Ahmadinejad is in Latin America this week and made Nicaragua his second stop on his 'tour of tyrants,' " she said. "Iran has turned to dictatorial regimes in the Western Hemisphere for help as responsible nations seek to increase their pressure on Tehran."
Ros-Lehtinen is one of many members of Congress pushing for tighter sanctions against Iran. The House approved two Iran sanctions bills in mid-December and sent them to the Senate.
