Democrats clamored for the speedy release of U.S. special counsel Robert Mueller's findings of his probe into whether President Donald Trump's 2016 campaign colluded with Russia. Now they finally have them, and they are confronted with a choice — stay on the attack or move on.

Progressives in the party used the report to renew their calls for action, but there was little immediate consensus on how to move forward.

Billionaire Tom Steyer, who has pumped millions of dollars of his own money into a campaign calling for Trump's removal from office, said lawmakers in the Democratic-led House of Representatives should begin the process of impeaching Trump, a Republican, based on the evidence amassed by Mueller.
