(CNN) - Texas Gov. Rick Perry drew parallels on Wednesday between the recent killing of a Texas district attorney and the security of his state's border with Mexico, though he provided no evidence to support the claim.
Perry, a candidate for the 2012 GOP presidential nomination, maintains the Obama administration has not put enough boots on the ground to secure the border.
Asked about theories that influential prison gang the Aryan Brotherhood of Texas was involved in that killing and another in January, Perry responded on Fox News, "I think it's obviously too early to be speculating on whether there is any direct contact but I think it's wise for us to not overlook any evidence that either may be superficial or otherwise.
"So they are here, they are active in this state. We know the drug cartels are very, very active in our country now," he continued.
Perry then said the issue "goes back ... to the whole issue of border security," specifically citing "the failure of the federal government to put the men and women, whether they are military or whether they are border patrol or whether they're working with the local law enforcement ... spend the dollars necessary to secure the border with Mexico."
The Southern Poverty Law Center, which monitors extremist groups, and the FBI say the brotherhood is a white supremacist criminal group whose activities involve murder, extortion and drug trafficking.
Perry said in the show that securing the border will "make sure that these individuals who are having rather free access at this particular point in time and whether it's taking money and guns into Mexico or drugs coming back and prostitution and sex trade back in to the United States."
"You secure the border and it makes it harder for these individuals to have access into this country as well as it addresses this issue that's hanging out on immigration," he said.
On Capitol Hill, lawmakers are currently negotiating a comprehensive immigration package.
Meanwhile in Kaufman County, Texas, authorities are investigating the March 30 killing of Mike and Cynthia McLelland, a district attorney and his wife, as well as any connections to the January 31 killing of prosecutor Mark Hasse.
The involvement of white supremacist groups are among many avenues the investigators are pursuing, according to reports.
"Unfortunately we live in a very dangerous world, whether it's in North Korea or whether it's right here in the state of Texas," Perry said.
