Conservative activist James O'Keefe has once again overpromised and underdelivered. This time, he claims his latest sting operation found Hillary Clinton's presidential campaign breaking the law, when in reality all that happened was the purchase of a t-shirt.

O'Keefe's Project Veritas Action accused the Clinton campaign on September 1 of allowing a Canadian tourist to launder money, in the form of allowing a t-shirt to be purchased.

In the video representatives of the Clinton campaign at a campaign event point out to a woman from Montreal that that the campaign can't take contributions from anyone who isn't American. An undercover activist from Project Veritas then makes the purchase on behalf of the Canadian.

As The Washington Post's Dave Weigel points out: “There are just two catches. One: No one's ever thrown the book at an American for purchasing merchandise from a campaign, then giving it to a foreigner as a gift. Two: The person who takes the Canadian's money and gives it to the Clinton campaign is the Project Veritas Action journalist.”

Weigel further notes, “Daniel Pollack, the director of communications at Project Veritas, argued that the on-camera swag exchange was part of a Clinton scandal continuum, comparable to the stories about foreign businessmen donating to Bill Clinton's foundation and expecting something from Hillary Clinton's state department.”

O'Keefe held a press conference September 1 to promote the video, where journalists reportedly asked him “Is this a joke?”

O'Keefe's crew has reportedly already made multiple other attempts to sabotage the Clinton campaign.

Project Veritas last month released a video showing their operative undercover with the Clinton campaign, discussing the registration process and whether they can register people who don't support Clinton.

A Clinton campaign staffer is then shown telling the Project Veritas operative that they will register anyone who asks, regardless of their presidential preference. As Time reported, “Nothing in the video shows the Clinton campaign violating the law, or the campaign's own policy. But Veritas claims, nonetheless, that the campaign is 'skirting the law' by first asking whether potential voters are supporters before making the registration offer. This approach to training volunteers is standard operating procedure across field campaigns, according to a Republican field staffer, who requested anonymity.”

Time reports that in addition to the t-shirt scheme, Project Veritas operatives approached the campaign and attempted to pass a cash donation to volunteers and interns while another told the campaign they wanted to illegally funnel donations through a third party.

These failure-laden sting attempts continue O'Keefe's pattern of using deceptively-edited videos, childish costumes, and sometimes committing crimes, in a futile campaign to attack the left. Even Fox News hosts have been embarrassed for O'Keefe, telling him to “give it a rest.”
