Story highlights Harvard professor Lawrence Lessig raised the $1 million he said was needed for him to seek the White House

Lessig is running a long-shot bid based on campaign finance reform

Washington (CNN) Campaign finance reform crusader Lawrence Lessig is set to announce his bid for the Democratic presidential nomination Wednesday, just a few days after he reached the $1 million fundraising goal he set for himself to launch a bid.

A Lessig spokeswoman told CNN Sunday that he would announce his run in Claremont, New Hampshire. The news came just a few hours after he tweeted about reaching his funding benchmark.

"WE DID IT!!! ($1M in < 4 wks) Thank you all for your support. Now, let's go #fixdemocracyfirst #getmoneyout" Lessig tweeted Sunday morning.
