Tom Arnold's Obsession with 'Taking Down' Donald Trump & Alleged Prescription Drug Abuse Caused Failed Marriage

Tom Arnold's estranged wife is laying out why her marriage ended with the actor, and she's claiming his ongoing drug addiction mixed with a fixation on President Donald Trump was a recipe for disaster.

Ashley Groussman Arnold just filed documents, obtained by The Blast, in her ongoing divorce with Tom, asking for the court to establish child custody and support, as well as spousal support for herself.

Ashley is asking for $6,783 per month for their two children, Jax and Quinn, as well as $9,036 per month in spousal support. She's basing those numbers off Tom's reported 2017 income of $604,680.

In her declaration, Ashley goes into great detail about the marital struggles she endured with the "True Lies" star, and constantly points to his alleged drug abuse as a reason for the split.

Ashley says Tom's behavior in the months leading up to their separation last year had been "increasingly erratic." She says that after the split, Tom agreed to move out of the family home when it was listed for sale in December, but he has not yet left.

Instead, Ashley moved out and rented a home during the divorce proceedings, but claims, "Toms communications with me throughout these dissolution proceedings have been hostile and accusatory."

She says, "I had hoped that things would cool down after I moved out, but that has not been the case." Ashley says Tom and her had agreed to try and attend co-parenting therapy sessions, but Tom was "irrational and crazy during the sessions, which proved to be worthless as Tom did the exact opposite of e everything we discussed during our sessions."

Ashley is accusing Tom of abusing prescription drugs, and writes, "Since separation, Tom has continued to engage in non-child centered conduct and abuse of prescription drugs." Specifically, she claims he's abusing Phentermine and Fenfluramine ... which is known as Fen-Phen.

The drug combination is typically used as an appetite suppressant, but is also considered a substitute for amphetamine. Ashley explains, "Phentermine is an amphetamine like drug that should not be prescribed to addicts due to its addictive nature. Tom should not be taking phentermine in the first place."

She claims Tom was supposed to be getting tested for phentermine, but has been dodging drug tests and is asking a court to force drug tests upon the star as part of a custody order.

Ashley also claims she confronted Tom about using prescription drugs in January 2019, and he "admitted that he had been using phentermine and Ambien."

Along with the drug use, Ashley believes Tom's obsession with President Donald Trump and the alleged "Trump Tapes" contributed to the demise of their marriage.

She writes, "Tom's fixation on 'taking down' Donald Trump was an ongoing issue in our marriage," adding, "For the past two years it has consumed his life and presented numerous safety issues for our family."

Ashley claims she was supposed to be featured on multiple episodes of "The Hunt for the Trump Tapes with Tom Arnold" on VICELAND, but thought it was unwise to continue feeding into the obsessive behavior.

She also says Tom lied to the Secret Service when they visited his home last year. "Tom told the Secret Service he did not have any guns in our home. This is untrue."

As we previously reported, Secret Service agents came to the Arnold's home last year after Tom challenged President Trump to a fight over Twitter. He received a strong scolding from the federal agents, but nothing else came of the matter.

Ashley says she does not want to stop Tom from seeing his children, but is asking for a custody evaluation and strict measures put in place that would keep everyone safe and accountable. She's also asking for Tom's custodial time to be monitored by a nanny.

Tom first filed divorce documents in February after confirming that he and Ashley had split after 9-years of marriage. At the time, he said, "For the last couple years we grew apart and have been moving in different directions, which is why at this time we have decided to end our marriage."

Ashley and her legal team, led by celebrity-attorney firm Hersh Mannis LLP, are requesting a hearing to discuss the entire ordeal.
