For all of the attention paid to former FBI Director Jim Comey's highly anticipated testimony before the Senate intelligence committee last Thursday, the most important constitutional law development from last week took place across the street (and three days earlier). The Supreme Court agreed to hear argument in Carpenter v. United States later this year—though exactly when, we're not sure.
At the heart of the dispute in Carpenter is the "third-party doctrine," the idea that we surrender our constitutional expectation of privacy whenever we voluntarily share non-content information with third-parties, such as our phone companies, internet service providers, financial institutions, and so on. The third-party doctrine brings together two distinct strands of Fourth Amendment theory—that individuals' voluntary conduct can effect a form of "consent" to government searches, and that individuals cannot assert a privacy interest in property they no longer own or possess.
Without an expectation of privacy in such information, the government may collect it without having to satisfy the Fourth Amendment—even if, in some cases, it must nevertheless satisfy more modest statutory requirements that Congress has imposed. Thus, although Edward Snowden's 2013 disclosure of the bulk telephone metadata collection prompted substantial public debate over the constitutionality of such surveillance, it is difficult to see the argument that it was unconstitutional, thanks to the third-party doctrine (the Second Circuit instead invalidated it on narrower, statutory grounds).
Although the phone records program is perhaps the most prominent example, there are hundreds of other government surveillance programs or protocols, the legitimacy of which is predicated on the third-party doctrine.
But as the Snowden disclosures also underscored, technology has dramatically changed the privacy implications of the third-party doctrine. As Justice Sonia Sotomayor , explained in a 2012 concurrence

Carpenter v. United States is going to potentially have a huge impact on an entire line of prior Fourth Amendment caselaw such as United States v. Jones (2012), Smith v. Maryland (1979), Katz v. United States (1967) and legal wrangling regarding warrantless access to voice and internet metadata by federal intelligence agencies.
It will be interesting to see if we continue along a rather well-established precedent of "third party" information and records being excluded from your "reasonable expectation of privacy" under the Fourth Amendment or if we break new ground in expanding the Fourth Amendment right.
I personally think the law and reason argues against Carpenter's appeal with regard to cell site location information (CSLI), but nonetheless, I'm licking my legal chops in anticipation of this one.
