Levi Johnston is firing back at Bristol Palin’s claims that he isn’t supporting their young son Tripp. After Palin filed papers for child support, Johnston’s lawyer told TMZ.com that the Playgirl model’s attempts to pay Palin were rebuffed. Johnston apparently invited Palin to his home to hand over $3,000 and mentioned that “it would be nice” if she came with their son. She never followed through. Palin—who the Johnston camp claims is now driving a $60,000 Escalade—preferred that Johnston mail the checks. Johnston’s attorney countered to TMZ: “Why should he have to do that? He’s not dangerous to her.” A manager for Johnston also claimed that he has still managed to pay at least $10,000 to support Tripp. A lawyer for Palin responded, “Bristol has set forth the facts regarding child support in her affidavit filed in court. The law in Alaska is clear: A parent is obligated to support his or her child. It is unfortunate Bristol has to seek court intervention in this regard."
