Trump aide's testimony indicates former president used classified documents inappropriately

Trump allegedly wrote to-do lists on backs of classified documents taken from the White House
Notecards with visible classification markings were found during FBI search of Mar-a-Lago
Trump told aide Molly Michael she didn't "know anything about the boxes" when federal agents wanted to question her
Michael grew concerned about Trump's handling of government document requests and later helped transfer materials to authorities
Trump maintains innocence but faces multiple federal indictments related to retention of classified information
