Priorities' February fundraising total represented a drop from the previous month, when it brought in $9.6 million. But the group has secured an additional $49 million in commitments, officials said. That brings its total fundraising and pledges for the cycle to $104 million.
"Our continued fundraising success means Priorities will be well prepared to fight back early and often against Republican attacks, take on the eventual GOP nominee, no matter who it is, and draw a sharp contrast between Hillary and her opponent," spokesman Justin Barasky said in a statement.
Several pro-Clinton super PACs are already compiling research on Trump's career, and plan to put resources into polling, focus groups and forensic accounting through the spring.
