Grayson, who lost in last year's Senate primaries to Patrick Murphy (who then lost to Marco Rubio), recently launched the site lockhimupnow.org, which solicits donations and encourages people to "blow the whistle on Trump."
"This is not an organization for people who have mixed feelings about Donald Trump, or who worry about whether VP Pence would be better or worse, or are willing to let Senate Republicans ‘investigate’ Trump and leave it at that," said Grayson in an email. "No. This is an organization for people who have decided that TRUMP MUST GO – and are ready to take action to make that happen."
Before he was a congressman, Grayson worked as an attorney specializing in whistleblower fraud cases aimed at Iraq War contractors.
