WASHINGTON (CNN) - The resignation of Obama administration figure Van Jones, following controversies over a petition he had signed and his comments about Republicans, did not come at the request of the president, the White House senior adviser said Sunday.
"Absolutely not - this was Van Jones' own decision," David Axelrod told NBC's "Meet the Press" when asked if the president had ordered the resignation.
The chairman of the House Republican Conference, Rep. Mike Pence of Indiana, had called for Jones to resign or be fired.
"I think Van Jones did the right thing," Pence said Sunday about the resignation. "His extremist views and coarse rhetoric have no place in this administration."
Jones has frequently been dubbed a "green-jobs czar" for the administration.
"The president should suspend any future appointment of so called czars while the administration and the Congress carefully examines the background and qualifications of the more than 30 individuals who've been appointed to these czar positions," said Pence, speaking to reporters. "And the Congress ought to initiate a thorough inquiry into the constitutionality of this practice which has spanned Republican and Democrat administrations."
In a statement Saturday night, the White House said Jones was giving up his post at the Council on Environmental Quality, where he helped coordinate government agencies focused on delivering millions of green jobs to the ailing U.S. economy.
"On the eve of historic fights for health care and clean energy, opponents of reform have mounted a vicious smear campaign against me," Jones said in the statement. "They are using lies and distortions to distract and divide."
