Vivek Ramaswamy's campaign stops all TV ad spending less than a month before Iowa and New...

A spokesperson for the GOP candidate’s presidential campaign said it has "the ability to be nimble and hyper targeted" in ad spending going forward.

Vivek Ramaswamy’s presidential campaign has stopped spending money on television ads and does not have any TV ad reservations booked, according to his campaign and data from an ad-tracking firm.

As recently as the first full week of December, the GOP entrepreneur’s campaign spent more than $200,000 on TV ads. Last week, it spent just $6,000 on ads — all of it on TV — figures from the firm AdImpact show.

Ramaswamy’s campaign says it is still spending money on ads, just not on TV.

“We are focused on bringing out the voters we’ve identified — best way to reach them is using addressable advertising, mail, text, live calls and doors to communicate with our voters on Vivek’s vision for America, making their plan to caucus and turning them out,” Tricia McLaughlin, the campaign’s press secretary told NBC News.

“As you know, this isn’t what most campaigns look like. We have intentionally structured this way so that we have the ability to be nimble and hypertargeted in our ad spending,” McLaughlin added.
