Gore tweets his approval @BarackObama

Former Vice President Al Gore approves of President Obama's pledge to fight climate change in a speech abroad, letting his thoughts be known via Twitter.

Gore tweeted Monday:
This is good to hear: http://tinyurl.com/cpd883 Thank you @BarackObama

The tweet from Gore represents a somewhat unusual public exchange between a sitting president and a former vice president. Also, it would appear that Obama (or at least his staff) is unlikely to receive the message directly; Obama's Twitter feed has remained largely dormant since inauguration.
