Or Laura Loomer. She's deleted a bunch of her Tweets that here highly critical of Kirk over the last few months, but the one mentioned in this article seems to still be there [1]. In case that one gets deleted, here is its full text [2].
While searching for more information on this I found an interesting link to something Grok wrote, answering the question of whether the shooter followed Loomer. It was quite interesting. No idea if any of it is true but given Musk's well known efforts to get Grok to favor the right it is sure amusing it would say this:
> Yes, based on reports and social media discussions following the assassination of conservative activist Charlie Kirk on September 10, 2025, the shooter, identified as 22-year-old Tyler Robinson from a "good Christian gun-loving MAGA family," followed Laura Loomer on X (formerly Twitter). Robinson was a vocal supporter of Donald Trump and appeared to have been influenced by far-right online rhetoric, including potential inspiration from Loomer's recent criticisms of Kirk as a "traitor" and "charlatan" who betrayed Trump. This detail emerged as investigators reviewed Robinson's social media activity after his capture on September 12, 2025. Loomer, a prominent far-right influencer, had posted multiple times in July 2025 attacking Kirk for hosting guests critical of Trump and engaging in "dialog with Democrats," which some speculate may have radicalized followers like Robinson. While the exact motive remains under investigation, the follow relationship aligns with broader patterns of intra-conservative online feuds escalating into real-world violence.

[2] > I don’t ever want to hear @charliekirk11 claim he is pro-Trump ever again. After this weekend, I’d say he has revealed himself as political opportunist and I have had a front row seat to witness the mental gymnastics these last 10 years.
> Lately, Charlie has decided to behave like a charlatan, claiming to be pro-Trump one day while he stabs Trump in the back the next.
> TPUSA was only able to thrive thanks to the generosity of President Trump.
> On the one year anniversary of the assassination attempt on Trump’s life, Charlie hosted @ComicDaveSmith at @TPUSA ’s SAS conference where Dave Smith was able to speak to a bunch of conservative youth at an organization that claims to be Pro-Trump.
> 3 weeks ago, Dave Smith called for President Trump to be IMPEACHED and REMOVED from office over his decision to blow up Iran’s nuclear facilities.
> Charlie played both sides of the Iran issue on his show as we all saw, because he wants to play to both sides of the aisle.
> The honorable thing to do is to have a position and actually defend it to the death instead of flip flopping.
> Smith said all of MAGA “should turn on Trump” and abandon him. He said this 3 weeks ago.
> See the clip below.
> TPUSA is definitely not pro-Trump. If they were, they certainly aren’t anymore.
> Out of all of the incredible pro-Trump voices out there who support the President, Charlie decided to host Dave Smith?
> It really is shameful. And I am honestly just disgusted by the nonstop flip flopping on the right.
