The 16 expiring clauses

AP news:

Sixteen provisions of the USA Patriot Act expire Dec. 31 if not renewed by Congress:

Section 201 - Gives federal officials the authority to intercept wire, spoken and electronic communications relating to terrorism.

Section 202 - Gives federal officials the authority to intercept wire, spoken and electronic communications relating to computer fraud and abuse offenses.

Most of them are not too controversial.
