MEXICO CITY, Mexico (CNN) -- Mexican authorities were searching Wednesday for two politicians accused of belonging to the Familia Michoacana drug cartel, which is blamed for killing more than 30 federal police officers in a series of attacks since Saturday.

Drug violence is up in Michoacan state, shown by recent attacks on police in at least a half-dozen cities.

Julio Cesar Godoy Toscano, elected July 5 to the lower house of Congress, is accused of being in charge of protection for the cartel, said Monte Alejandro Rubido Garcia, head of the National Public Security Council. Godoy Toscano is half-brother to Michoacan's governor, Leonel Godoy Rangel, who Wednesday urged his relative to surrender.

Authorities also said they are searching for Saul Solis Solis, alias "El Lince," who lost his bid for a congressional seat this month. He is accused of being in charge of the cartel's activities in the Huacana area. Solis is a cousin of Enrique Plancarte Solis, a Familia Michoacana leader, Rubido said.

Both suspects report to Servando Gomez Martinez, known as "La Tuta," Rubido said.

Godoy Toscano was elected as a member of the opposition Democratic Revolutionary Party, known as the PRD. The party said Wednesday it would not protect Godoy Toscano or any member who has broken the law.

Godoy Rangel, the Michoacan governor, told a radio station there's nothing he could do to help his fugitive brother.

"I cannot protect anyone, not even my children," the government-run news agency Notimex quoted him as saying.

He said Wednesday that he has no intention of resigning, because he has done nothing wrong, Notimex said.
