Barack Obama appears to use VERY crude hand gesture to mock Trump's 'weird obsession' with size as he leads chants of 'yes she can' for Kamala.. after he 'helped' force Biden out

 Former President Barack Obama compared Donald Trump to an annoying neighbor with a leaf blower and called out his 'weird obsession' with crowd sizes in his convention speech Tuesday. Obama called for passing the torch to VP Kamala Harris, and spoke about the risk of being upstaged by former first lady Michelle Obama.
