From The DC:

President Barack  Obama used the online springboard provided by Reddit to dive into the media  crush at the GOP convention, with a skillfully executed call for a  constitutional amendment to curb the free-speech of wealthier people and  corporations.

“I think we need to seriously consider mobilizing a constitutional amendment  process to overturn Citizens United. … Even if the amendment process falls  short, it can shine a spotlight of the super PAC phenomenon and help apply  pressure for change,” Obama said during 4:30 p.m. EST online event.
