got this from a "fact checker" that labelled it false but if you read it they agree

with the act President Trump will need congress approval before he can do it

While Callesto presents his claim as if he is quoting directly from the bill, the phrase “nullifies the President’s use of the Insurrection Act” does not appear anywhere in the NDAA, the full text of which can be found here.

Broadly speaking, the Insurrection Act, which was originally passed in 1807 and has been amended several times since, authorizes the use of military force to suppress insurrections. The amendment showcased in this viral tweet would not have “nullified” the Insurrection Act. Rather, House Amendment 833, which was agreed to in the House of Representatives back in July 2020, would have required a president to make “certifications to Congress” before invoking the Insurrection Act.
