This is what obama told his friend about donald trump

I'm not aware of any specific quote or statement made by Barack Obama about Donald Trump to a friend. As a former President, Obama has made many public statements about Trump, but I'm not aware of any private conversation or quote that has been shared publicly.

However, it's worth noting that Obama has made some public comments about Trump that have been reported in the media. For example, in 2017, Obama said that Trump's presidency was "a symptom, not the cause" of the divisions in American society, and that Trump's rhetoric was "a threat to our democracy." He also criticized Trump's handling of the COVID-19 pandemic, saying that it was "a chaotic and incompetent response."

It's also worth noting that Obama has not publicly spoken about Trump in a way that is derogatory or disrespectful. While he has certainly disagreed with Trump's policies and actions, he has also emphasized the importance of civility and respect in political discourse.

If you're looking for specific quotes or statements made by Obama about Trump, I'd be happy to try to help you find them.
