Donald Trump’s campaign launched its first general election TV ad on Friday in battleground states where the Republican nominee trails Democratic rival Hillary Clinton, hitting her for a “rigged” system. 

The commercial will run in Florida, Ohio, North Carolina, and Pennsylvania until Aug. 29, NBC News reported.

The $4 million Trump is spending in those states pales in comparison to the $61 million Clinton’s campaign has spent so far.

The Trump ad focuses on security and is themed around Trump’s “Make America Safe Again” campaign slogan introduced at the Republican National Convention.

In opens with the line, “In Hillary Clinton’s America, the system stays rigged against Americans,” followed by shots of men, their faces blurred out, representing undocumented immigrants.

The shots then switch to images of what a Trump presidency would look like: a border arrest, military men and happy families.

Trump has hinted that if he were to lose the election, it would be because of the system in place that is “rigged” against him.
