WATCH: Kari Lake Releases Hard-Hitting Attack Ad After Securing Senate Nomination

The campaign for Arizona's Republican Senate nominee Kari Lake released a hard-hitting ad focusing on the border policies of the Biden-Harris Administration, all of which have been supported by her opponent, U.S. Rep. Ruben Gallego (D-AZ).

The ad, titled "Ruben and Kamala: Bad For America" is part of a joint $10 million ad buy with the National Republican Senatorial Committee (NRSC), Lake's campaign announced in an email.

The Lake Campaign's latest attack ad begins by pointing to the fact that Gallego has voted with "Joe and Border Czar Kamala" 100 percent of the time. "Including their radical border agenda," a narrator continues.

It then cuts to a clip of then-candidate Harris saying "we're not going to treat people who cross the border as criminals." The vice president has in the past called for the decriminalization of illegal border crossings into the United States.

The ad follows up Harris' quote with one from Gallego in which he stated that Congress will not support a border wall that is "not needed."

"Ruben Gallego and Kamala Harris; bad for the border, bad for Arizona, and bad for America," the narrator concludes.

In a statement following the ad release, the newly-minted Republican nominee again took aim at both Gallego and Harris.

"Radical Ruben Gallego has a long record of supporting open-borders policies and voting against efforts to secure our border," Lake said.

"He supported Joe Biden and his border czar Kamala Harris as they created this national security & humanitarian crisis. Ruben and Kamala are bad for the border, bad for Arizona and bad for America," she added.

The new Lake Campaign ad follows a trend of Republican Senate candidates tying their opponents to Harris' failed border policies. I'm Pennsylvania, Dave McCormick has blanketed the airwaves with ads tying Senator Bob Casey (D-PA) to the Biden-Harris Administration's record on inflation, energy police and illegal immigration, among other things.

Immigration in particular projects to be one of the most important issues for voters in November, as evidenced by months of polling trends. A recent survey conducted by the pro immigration Chicago Council of Global Affairs found that more than half of Americans view mass migration as a "critical threat.
