Former ambassador John Bolton stopped by Gov. Bob McDonnell’s office in the Patrick Henry Building on Tuesday while he was in town to give a speech.

The two spoke for about 30 minutes about McDonnell’s record in Virginia, national public policy and other issues, the governor’s spokesman Tucker Martin said. The two men have spoken before.

Did the two also speak about politics? McDonnell has been mentioned as a possible Republican vice presidential candidate and, apparently, Bolton is getting some buzz of his own as a possible presidential contender.

Bolton was to speak about foreign policy challenges for President Obama’s administration at the SunTrust Bank Building, just off Capitol Square (home to Sen. Mark Warner’s Richmond offices.)

Bolton, who served as ambassador to the United Nations from 2005-2006, now researches U.S. foreign and national security policy at American Enterprise Institute and is a Fox News contributor.
