"Our globe-trotting president needs to stop and take a break and quit gallivanting around," said Miller, a southern Democrat well known for attacking his own party. "I think Rahm Emanuel ought to get some Gorilla Glue and put it in that chair in the Oval Office and say ‘Sit here awhile.’”
Speaking to a group of mostly Republican lawmakers in Atlanta on Thursday, Miller called Obama's decision to close the military prison at Guantanamo Bay "nuts" and likened the federal stimulus package to a Paris Hilton spending spree.
It wasn't the first time Miller has bashed his party's leaders. He earned the ire of fellow Democrats when he took the podium at the 2004 Republican National Convention and accused his party of being soft on national security.
In a famous line from that speech, Miller listed a range of defense programs that he said then-candidate John Kerry opposed.
"This is the man who wants to be the Commander in Chief of our U.S. Armed Forces?" he asked. "U.S. forces armed with what? Spitballs?"
Two black leaders who know Miller well said they were not offended by Miller's latest "Gorilla Glue" zinger, which came hours before the nation's first African-American president addressed the NAACP.
The Rev. Joseph Lowery, a civil rights leader, noted the glue is a brand name. "I ignore it," he said. "I consider the source and go about my business."
Democratic State Rep. Tyrone Brooks, who leads the Georgia Association of Black Elected Officials, said he wasn't bothered by Miller's comment, but that it came a few years too late.
"It would have been much more appropriate that he suggest that Karl Rove used some Gorilla Glue on George Bush and Dick Cheney," said the Atlanta Democrat.
Miller, a former two-term governor in Georgia, won praise from the state's black leaders during his tenure for appointing minorities to high-ranking positions, including his naming of Leah Ward Sears to the state Supreme Court. She later became the first black female to serve as chief judge of any state's top court.
