Former President Donald J. Trump has become entangled in a web of federal and state prosecution, and now faces 91 criminal charges in four separate state and federal cases.

Political action committees supporting him have spent more than $27 million on legal costs in the first six months of 2023, and he has recruited a small army of lawyers to defend him. Here are a dozen of the prominent figures and their bills paid by Mr. Trump’s Save America PAC.

Fees: $353,000 paid to his firm from April to June 2023

Mr. Trump hired Mr. Blanche in April. His firm has been paid $353,000 for legal work by Save America, according to federal filings. Mr. Blanche is representing Mr. Trump in the Stormy Daniels hush money case, the federal classified documents case and the federal election interference case.

Fees: $195,000 paid in 2022

Boris Epshteyn, a top adviser and longtime ally of Mr. Trump, serves as something of an in-house counsel, helping to coordinate the former president’s many lawyers. He was paid $195,000 by Mr. Trump’s PAC in 2022, though not specifically for legal consulting, and at least $30,000 by his 2024 campaign. He is thought to be one of six unnamed co-conspirators in the federal election interference case and has been enmeshed in other Trump investigations as a witness. He has been represented by Mr. Blanche, and had recommended adding Mr. Blanche to Mr. Trump’s legal team.

Fees: $5.8 million in 2022 and the first six months of 2023

Fees: $465,000 in the first half of 2023

Susan R. Necheles was counsel to Venero Mangano, the late Genovese crime family underboss known as “Benny Eggs,” and recently represented Jeremy Reichberg, a former fundraiser for Mayor Bill de Blasio of New York, in a federal bribery case. She has been defending Mr. Trump and the Trump Organization in a variety of investigations since 2021. Mr. Trump’s PAC paid her firm $465,000 in the first six months of 2023.

Stephen Weiss worked as an associate at the law firm Cadwalader, Wickersham & Taft for six years before joining Mr. Blanche in June at his firm. Mr. Weiss was present at a pretrial hearing for Mr. Trump in the documents case last month.

Fees: $212,000 in 2022 and the first half of 2023

Lindsey Halligan was part of an aggressive effort by Mr. Trump’s legal team last year to have a special master appointed to review documents the F.B.I. had seized in the raid on Mar-a-Lago. She was also part of a team of lawyers who met with Justice Department officials in June in a final effort to stave off charges in the documents case. Mr. Trump’s PAC paid her $212,000 from June 2022 to June 2023.

Fees: $288,000 in 2022 and the first half of 2023

John Lauro formally joined Mr. Trump’s legal team in the election interference case earlier this month, although he had earlier advised the former president on legal matters. He was paid $288,000 for his legal work in 2022 and the first six months of 2023 by Mr. Trump’s PAC. He accompanied the former president to his arraignment in the federal election interference case earlier this month.

Mr. Lauro gained notoriety for representing Tim Donaghy, a former N.B.A. referee who pleaded guilty to betting on games and taking payoffs from gamblers. He also previously worked as a federal prosecutor in Brooklyn.

Fees: $816,000 in 2022 and the first half of 2023

Drew Findling, a prolific figure in the world of Atlanta rap known as the #BillionDollarLawyer, joined Mr. Trump’s legal team a year ago. Mr. Findling has represented an array of famous rap stars — including Cardi B, Gucci Mane and Migos — and is well regarded for his defense work, with decades of trial experience ranging from high-profile murder cases to local political corruption scandals in Georgia. Mr. Trump’s PAC paid his firm $816,000 from July 2022 to May 2023.

Marissa Goldberg, a partner at Mr. Findling’s law firm, has worked alongside Mr. Findling and Ms. Little in an effort to quash the entire Georgia election case and to disqualify Fani T. Willis, the Fulton County district attorney leading the case.

Fees: $100,000

Jennifer Little began her career as a prosecutor in DeKalb County, Ga., before becoming a partner at the firm Fried Bonder White. She later started her own firm, Jennifer Little Law. Like Mr. Corcoran, Ms. Little was compelled to testify about her legal work representing Mr. Trump in the federal documents case. She was paid $100,000 by Mr. Trump’s PAC in April 2022.
