U.S. Sen. Luther Strange released a new ad on Wednesday touting the endorsement he received less than 24 hours before from President Trump.

The 20-second spot, posted on Strange's You Tube channel, is a straightforward presentation of Trump's backing with no voice over. The ad contains the text of Trump's endorsement tweet and twice reminds viewers to vote Aug. 15 in the Senate Republican primary.

Meanwhile, before the Trump endorsement on Tuesday night, Strange challengers Mo Brooks and Roy Moore announced new ads themselves on Tuesday afternoon in emails sent just four minutes apart.

And the similarities only grew stronger from there.

With the nearly mirror-image 30-second spots launched one week before the Aug. 15 Senate Republican primary, the ads might arouse plagiarism concerns were two classmates in school to submit them to their teacher.

The gist of both ads are that the Washington establishment is relentlessly pushing Strange and how both Brooks and Moore are independent of that arena, so to speak.

But as Moore seeks to protect what's believed to be a safe spot in the expected GOP runoff and as Brooks, according to polls, is in a virtual tie with Strange for the final runoff spot, the challengers hit on the same themes:

Both ads open with visuals of the U.S. Capitol.

Both ads hammer Senate Majority Leader Mitch McConnell, who is backing Strange.

Both ads used the phrase "spending millions" of dollars to slam the financial support Strange has received from the McConnell-controlled Senate Leadership Fund.

Both ads hit McConnell on the Senate's failure to repeal the Affordable Care Act, also known as Obamacare.

Brooks' ad dubs McConnell the "swamp king" while Moore's ad says McConnell is controlling the "slime machine."

Brooks' ad tells voters to "send D.C. a message" while Moore's ad instructs to "send them all a message."

As for differences in the ads, Moore does not mention Trump while six seconds in Brooks' ad tells of his 93 percent voting record with Trump and includes a photo of Brooks and Trump together in the Oval Office.

And Moore does not mention Strange in the ad, firing the barbs instead at McConnell for "bearing false witness" in an attack ad.

"Why?," the ad asks. "We know why. We all know why."

Brooks' ad said McConnell is helping his "lapdog, Luther Strange, hijack our Alabama primary."

Brooks' ad also scrolls the names of high-profile endorsements while Moore's makes no mention of endorsements.
