Daniel Horowitz

In March 2017, police were called when radio show host, Michael Savage was thrown to the ground outside of a Marin County restaurant. Savage had been a vocal supporter of Donald Trump and Horowitz represented Savage telling the press that he was investigating "whether it had anything to do his client’s political views and his support of Trump".

In 2016, Horowitz represented former Pittsburg, California, police officer, Wade Derby who exposed how the department falsified crime statistics by systematically reporting criminal conduct as suspicious circumstances. This lowered the crime statistics and made the department appear to be doing a better job than it was. On July 6, 2016, a New York Times article followed the current status of Horowitz' client, Pavel Lazarenko, the former Prime Minister of Ukraine. The article described how Horowitz and a team of lawyers were fighting the United States government over millions of dollars that were seized as part of the criminal prosecution of Lazarenko more than 15 years ago.

In a 2016 case, Horowitz represented the founder of a white prison gang (Coby Phillips). Phillips read Elie Wiesel's book Night about Wieisel's Holocaust experiences, and he was so moved that he renounced his swastika tattoos and ordered his group members to stop using that symbol. In March of 2018, that prosecutor left the district attorney's office and went into practice with Horowitz.

Horowitz also represented Dr. Wilmer Origel, a chiropractor who was accused of 11 felony charges, of practicing anesthesiology without a medical license, money laundering, and insurance and workers' compensation fraud totaling $5 million. The case became controversial because Horowitz's legal fees were paid by local taxpayers once his client ran out of money to pay for his own representation. Many felt Horowitz's bill would rapidly deplete county funds that were "used to pay local attorneys who represent criminal defendants too poor to hire lawyers themselves." Horowitz argued that the fees paid to appointed attorneys in Stockton were so low that it almost guaranteed that the clients would receive substandard representation and won the battle over fees. The jury hung, 10–2, for acquittal and all charges were later dismissed. The same issue arose in 2019 when Horowitz sought appointment to represent a physical therapist against fraud charges and he asked for $750 per hour in fees.

On October 15, 2005, he found his wife dead at the mobile home in Lafayette where the couple had lived since they were married. At the time, Horowitz was defending Susan Polk in her murder trial. Two days after the murder, Horowitz was interviewed by MSNBC anchor Dan Abrams who reported that Horowitz said "his wife—quote—'fought like hell,' as indicated by defensive wounds on her body." A local 16-year-old boy, Scott Dyleski, was arrested within days; he was convicted of killing Pamela Vitale and sentenced to life imprisonment without the possibility of parole in 2006. Scott Dyleski's mother was also arrested and charged with covering up the murder. On June 9, 2016, federal judge Susan Illston rejected Dyleski's claims of innocence and ineffective assistance of counsel. In rejecting claims of prejudice, Judge Illston stated that the prosecutor properly argued that: "I hope you remember that as you are reflecting on the evidence in this case, that she is about as innocent a victim as you can have in a criminal case," and by characterizing Vitale as "a woman that virtually everybody in that neighborhood loved or certainly liked."

Horowitz became a national media personality when he became a regular television commentator during the 2004 Scott Peterson trial. Since the Peterson trial, Horowitz has been a commentator on other high-profile cases such as the Michael Jackson trial, the Melissa Huckaby trial in Tracy, California, and the Anna Nicole Smith case. He has appeared as a regular legal commentator on CNN, MSNBC and Fox News. In 2015, Horowitz was a commentator on the Orville Fleming case involving a California Fire Chief who killed his girlfriend and claimed that he was a "zombie" at the time of the killing and therefore was not guilty of premeditated murder. Horowitz was skeptical of the defense and the defendant was convicted.

In 1999, Horowitz represented Sean Twomey, in what the Bureau of Alcohol, Tobacco & Firearms claimed was running the "nation's largest black-market weapons trafficking case. A decade later (2012), Horowitz criticized the federal government's Mexican based gun investigation called "fast & furious", where real weapons were sold to gangs so that the federal government could trace the weapons flow. Horowitz claimed that the publicity was political and the scope of the case was blown out of proportion. Horowitz represented conservative talk show host, Michael Savage, in Savage's lawsuit against CAIR. The judge sided with CAIR and dismissed Savage's lawsuit in 2008. In 2012 he won Savage's lawsuit against syndicator TRN and released Savage from his contract with that network.

Horowitz met Pamela Vitale when she worked in Hollywood as an independent movie producer. He had written a screenplay about one of his cases and was shopping it around. They married in 1994.

Horowitz was born in New York City. He received his Bachelor of Arts from Hampshire College. In 1980, he earned his Juris Doctor (J.D.) from Southwestern University School of Law in Los Angeles, California. He was admitted by the State Bar of California that same year. He is a Certified Specialist in Criminal Law (the State Bar of California Board of Legal Specialization). Horowitz married Valerie Northup, his third wife, in June, 2007. Horowitz and Northrup had a son, Isaac Aaron, in April, 2009.

Horowitz also represented Kimberly Bell, the former girlfriend of San Francisco Giants slugger, Barry Bonds. Bell testified against Bonds before the Grand Jury that later indicted Bonds for perjury arising out of his denial of steroid use. Horowitz also represented Steve Williams, the man who ended up with Barry Bonds' 700th home run baseball. Various other fans claimed that they were entitled to the ball.
