The lawyer who initiated the effort to remove Fani Willis from the Georgia election interference case against Donald Trump walked state lawmakers through her investigation into the Fulton County district attorney's romantic relationship with a special prosecutor and why she believes it creates a conflict of interest.

Ashleigh Merchant, who represents Trump co-defendant Michael Roman, was subpoenaed to appear Wednesday before a specially appointed Georgia state Senate committee tasked with investigating whether Willis engaged in misconduct. Willis' relationship with special prosecutor Nathan Wade, whom she hired to manage the election interference case, was first exposed in a motion filed on Jan. 8 by Merchant that seeks to toss out the indictment and to bar Willis and her office from continuing the prosecution.
