"The comments were outrageously inappropriate," he told Sky News on Sunday, but noted Mr Trump had apologised for the remarks he made in 2005.
But Senator Cormann declined to say whether Mr Trump should step down from the presidency race, leaving it to "our friends in the United States" to resolve the issue.

"These comments cannot be excused, or dismissed," he said.
