The British are coming.

The U.K. Labour Party is organizing a visit by 100 former and current staff to boost Vice President Kamala Harris in battleground states across the U.S., an unusual effort by British liberals to bolster their political allies across the pond.

Sofia Patel, the head of operations for the Labour Party, said the staffers will be heading to North Carolina, Nevada, Pennsylvania and Virginia in the “next few weeks.”

“I have 10 spots available for anyone available to head to the battleground state of North Carolina — we will sort your housing,” she said in a midweek posting on LinkedIn.

The effort coincides with heightened concerns about outside meddling in U.S. elections.

The Biden-Harris administration has repeatedly warned about foreign interference, particularly from Russia, and has taken formal action to crack down on online trolls guided by Moscow. Democrats have also criticized former President Donald Trump for hosting Hungarian President Viktor Orban, citing reforms in his country viewed as undemocratic.

Sen. Tom Cotton, Arkansas Republican and no fan of Britain’s liberal party, called Labour’s effort “yet another reason to vote for President Trump,” while online commenters wondered aloud if it is even legal.

While there are strict guardrails around foreign contributions or interference in U.S. elections, foreign nationals can boost U.S. candidates under certain conditions.

The Federal Elections Commission told The Washington Times it cannot comment on specific situations but referred to its webpage on the topic.

“Generally, an individual (including a foreign national) may volunteer personal services to a federal candidate or federal political committee without making a contribution,” the webpage says. “The [Federal Election Campaign Act] provides this volunteer ‘exemption’ as long as the individual performing the service is not compensated by anyone.”

For instance, the FEC said a foreign national could provide an uncompensated musical concert so long as the artist paid for all of his or her costs and did not participate in decision-making by the campaign.

Also, the “commission held that a foreign national could attend, speak at campaign events for a federal candidate, and solicit contributions to the campaign,” the FEC webpage says. “However, the Commission cautioned that the foreign national could not manage or participate in any of the campaign committee’s decision-making processes.”

Election experts say foreign nationals are free to travel to the U.S., akin to tourism, and raise a Harris sign or talk politics, but the effort could run afoul of the law if they attempted to coordinate with the campaign or if a third party paid for their trip and accommodations.

The Harris campaign has not publicly acknowledged Labour’s effort, and Ms. Patel’s posts about the trip did not signal any intent to coordinate with the campaign. The short posts did not say how travellers’ expenses would be covered.

The Washington Times reached out to the email account listed by Ms. Patel for more details about the trip.

The center-left Labour Party won a landslide victory in U.K. elections earlier this year, ending 14 years of conservative leadership. The new prime minister, Keir Starmer, met with President Biden at the White House in September.
