WASHINGTON — In anticipation of Rep. Martha McSally potentially jumping into the Senate Republican primary against Kelli Ward, a pro-Trump advocacy group is targeting her stance on immigration.

Great America Alliance rolled out amnestymartha.com on Friday, which also includes an ad the group will be running digitally. The group has endorsed Ward and Eric Beach, who chairs the group, works as a strategist for Ward’s campaign.

Friday's ad hits McSally for votes it says reveal she supports "amnesty for illegals."

The ad points to McSally's vote against an amendments to a 2015 Department of Homeland Security Appropriations bill that would defund then-President Obama’s program that shielded 800,000 undocumented immigrants who came to the U.S. as children from deportation.

The ad also highlights McSally’s vote against an amendment to the 2015 National Defense Authorization Act bill that would have removed a provision that encouraged protections for undocumented immigrants who serve in the military.

The third vote was in favor of a bill that stripped out all the controversial amendments to the 2015 Department of Homeland Security Appropriations bill.

"This group should know fake news when they see it. The real news is that Martha votes for the President’s agenda more than anyone else in Arizona. Fact," Anthony Barry, McSally's campaign manager told USA TODAY. "Martha is one of the strongest members on border security in Congress as the Chairwoman of the border security subcommittee."

Barry pointed to other votes McSally had taken that were tough on immigration, including: cuttings funds to sanctuary cities, constructing a border wall along the souther border and increasing the number of Border Patrol and ICE agents.

McSally is part of a working group assembled by House Speaker Paul Ryan, R-Wis., to figure out how best to address recipients of the Deferred Action for Childhood Arrivals program. President Trump reversed the Obama-era order in September, but gave Congress six months to find a solution.

The group includes Republicans from various factions of the party. McSally, who is also in a bipartisan working group called the Problem Solvers Caucus that is working on immigration, represents one of the more moderate members working on the bill.

It is the second broadside against a potential McSally Senate run in a week.

Last week, a political-action committee aligned with the fiscally conservative Club for Growth and other national "tea-party"-aligned groups such as the Senate Conservatives Fund, FreedomWorks and Eagle Forum put out a joint statement opposing McSally.

The group said McSally "masquerades as a conservative on the campaign trail but time and time again ... has abandoned conservative principles."

McSally has not commented on her political future since Flake announced he would not seek a second term in the Senate. But she made clear in a meeting with other Republicans in the state’s delegation last week that she was strongly considering a Senate run.

If McSally decides against running for the Senate and instead opts try and hold her House seat, she faces a competitive race in the moderate southern Arizona district that was held by Rep. Gabby Giffords.
