Washington (CNN) A former Trump campaign staffer who accused Donald Trump of forcibly kissing her without her consent in 2016 has dropped her lawsuit against the President, saying it's difficult to pursue "justice against a person with unlimited resources."

"I have made the difficult decision not to pursue my claims at this time," Alva Johnson, who worked for the campaign in Alabama, said in a statement provided to CNN Thursday by her attorney.

"I am facing a judge who openly questions whether the kiss is worthy of a federal lawsuit and has determined that Mr. Trump's history of such behavior is not relevant, and I've endured on-going threats to my safety," Johnson said. "I've decided for the sake of my family that I will not continue with the case at this time."

The Daily Beast was the first to report on Johnson's decision to end her lawsuit.

Trump's attorney, Charles Harder, said in a statement Thursday that Johnson, by "giving up the case, represents total victory for President Trump, and fully vindicates him of Johnson's false accusations."
