Tulsi Gabbard says Iran could produce nuclear weapons "within weeks", months after she testified before Congress that the country was not building them. The US Director of National Intelligence said her March testimony - in which she said Iran had a stock of materials but was not building these weapons - had been taken out of context by "dishonest media".
I doubt countries are sharing intel with the US given how Trump and his minions handle classified information.
So she probably wouldn’t know whether or not Iran was building nukes.
Iran is a ally of Russia, so if she did have information on Iran building nukes Putin probably wouldn’t let her say. Trump probably overruled that because he saw Israel was winning and he wanted to take credit for the win.
What a shitshow the US has become.
