An explosive plea agreement by Donald Trump's former lawyer may give porn star Stephanie Clifford a second act in the courtroom and renew her effort to question the president under oath.

The case is "far from over," her lawyer, Michael Avenatti, said in an interview. "I will not rest until America knows the truth about what happened."

Clifford, whose stage name is Stormy Daniels, filed a lawsuit in March against the president and the lawyer, Michael Cohen, alleging an agreement she signed to keep quiet about an alleged affair with Trump in exchange for $130,000 was void because it violated campaign finance laws.
