Former presidential candidate Ralph Nader says President Obama should be impeached for committing "war crimes" in Iraq and Afghanistan.
The consumer advocate and former presidential candidate said in an interview that aired Friday that Obama has committed "war crimes" on the same level as President Bush.
Nader's comments came before the U.S. on Saturday launched military strikes into Libya, but they are among the toughest criticisms Obama has endured from the left.
The consumer advocate participated in an anti-war demonstration outside the White House this weekend, during which more than 100 protesters were arrested.
The U.S. sought the passage of a U.N. Security Council resolution and commitments from European and Arab nations before taking action in Libya to thwart the country's leader, Col. Moammar Gadhafi, from killing civilians amidst a rebellion against his regime.
Nader's comments, however, were mainly directed at Obama's prosecution of the Afghanistan war. Some liberal activists have objected to Obama's decision to escalate the war and are unhappy with government's treatment of Bradley Manning, the Army private accused of leaking classified documents to the organization WikiLeaks.
"[Bush officials] were considered war criminals by many people. Now, Barack Obama is committing the same crimes," Nader said. "In fact, worse ones in Afghanistan. Innocents are being slaughtered, we are creating more enemies, he is violating international law."
Obama appears to be facing growing resistance from the left over his administration's foreign policy.
Anti-war filmmaker Michael Moore sharply criticized the president's authorization of military strikes in Libya and a cadre of liberal House Democrats are questioning the constitutionality of the Libya operation.
