"This was a setup & politically motivated", Avenatti tweeted. According to TMZ, the customer Daniels allowed to "motorboat" her turned out to be Columbus police officer Mary Prather. "We will fight all bogus charges", Avenatti tweeted.
"This is ridiculous that law enforcement resources were used to conduct this sting operation", he said. "There has to be higher priorities".
The arrest happened because Daniels, legal name Stephanie Clifford, purportedly violated an OH law by allowing a patron to touch her.
She was released on bail before 6:00am (local time) - court records show Daniels posted $US6,000 ($8,112). We also expect that she will be charged with a misdemeanor for allowing "touching".
Columbus police tell CBS News they're not aware of Daniels being arrested, and as of early Thursday, Daniels wasn't being held by the Franklin County Sheriff's Department.
An Ohio law, known as the Community Defence Act, prohibits anyone who is not a family member to touch a nude or semi-nude dancer.
Stormy Daniels looked less than pleased in her mugshot after she was booked for allegedly grabbing an undercover cop's backside at a strip club overnight. Reached by The Washington Post early Thursday, a representative for Sirens strip club refused to comment.
Just days before the 2016 election, Cohen paid Daniels $130,000 in exchange for her silence.
Avenatti also shared a statement from Stormy herself in which she apologized for not being able to go on with a scheduled show for Thursday night in Columbus. Trump has denied the accusation. Trump has said he personally reimbursed Cohen for that payment.
Through White House officials, Trump has denied the affair, although Cohen has admitted paying Daniels $130,000 as part of the agreement.
