The six-month review of Trump's regulatory agenda by the American Action Forum shows the federal government practically slamming the brakes on regulation. The number of new rules is now at a record low, according to the study, in sharp contrast to the start of the Obama administration. 

"If you look at what's happening in the first six months for President Trump compared to President Obama, it's staggering," group president Douglas Holtz-Eakin told "Fox & Friends" on Friday.

On the campaign trail, then-candidate Trump promised that "for every new regulation, we're going to cut two," and to "get rid of all the unnecessary regulations."

The data from AAF, a conservative-leaning think tank, shows a total of 27 rules have been withdrawn so far this year, which is slightly lower than the 41 rules that were approved.
