With Rudy Giuliani being called to court in Georgia, is it more a political move or a legal move following the 2020 elections?

"When politicians are involved, there are almost always political calculations, but there’s a lot of information suggesting there may be problematic behavior that he was heavily involved with. There are reports of investigations involving several possible Georgia law violations: solicitation of election fraud, making false statements to local officials, conspiracy, racketeering, violations of oath of office and involvement in violence or threats of violence, according to Voice of America."
