The quote, in my best opinion , is from this letter:
'. In a letter sent to key Senators while Congress was deliberating over this legislation, Assistant Attorney General Daniel J. Bryant, of DOJ's Office of Legislative Affairs, openly advocated for a suspension of the Fourth Amendment's warrant requirement in investigating foreign national security threats.7 The Bryant letter brazenly declares:
As Commander-in-Chief, the President must be able to use whatever means necessary to prevent attacks upon the United States; this power, by implication, includes the authority to collect information necessary to its effective exercise.... '

Of course the President must be able to use whatever means are "neccessary"- in the actual meaning of the word- 'irreplaceable'.
There is no obstruction to that in the Constitution.

It's the use of unneccessary or unConstitutional means that are a danger.
