Valerie Plame Wilson is fundraising to buy a controlling share of Twitter so that she can ban President Trump from the social media platform.

"From emboldening white supremacists to promoting violence against journalists, his tweets damage the country and put people in harm's way," Wilson wrote on her GoFundMe page. "But threatening actual nuclear war with North Korea takes it to a dangerous new level."

Wilson, who was revealed to be a covert CIA operations officer in a 2003 leak, slammed Twitter executives for ignoring calls to enforce the company's own community standards and delete Trump's account.

But Wilson's progress has been slow: She has raised almost $3,000 since the page was set up on Aug. 16, well short of her $1 billion target.

She acknowledged the enormity of task, facing institutional barriers and a stock price that has stabilized at about 16 cents.

A single shareholder or a group acting in kind can gain a controlling interest in a company when they buy 50 percent of its outstanding shares plus one. Twitter currently has about 731 million outstanding shares.

"If we can't get a majority interest, we'll explore options for buying a significant stake in the company and champion this proposal at the annual shareholder meeting," Wilson wrote of Twitter, which is worth about $11.8 billion.

"If that's impossible for any reason or if there is a surplus from this campaign, 100 percent of the balance of proceeds will be donated to Global Zero, a nonprofit organization leading the resistance to nuclear war."
