A woman who worked on Donald Trump's presidential campaign sued the president on Monday, accusing him of kissing her without consent before a 2016 rally in Tampa, Florida.

Alva Johnson said in the lawsuit, filed in U.S. District Court in Florida's Middle District, that the alleged incident was "part of a pattern of predatory and harassing behavior towards women" by Trump.

"This accusation is absurd on its face," White House spokeswoman Sarah Sanders said in a statement. "This never happened and is directly contradicted by multiple highly credible eye witness accounts."
