From the introduction to Presidential Terms and Tenure: Perspectives and Proposals for Change (R40864, Apr. 15, 2019):

The length of the President’s term and the question of whether Presidents should be eligible for reelection were extensively debated in 1787 at the Constitutional Convention. Late in the proceedings, the delegates settled on a four-year term for both President and Vice President but did not place a limit on the number of terms a President could serve.

From the introduction to Can the President Close the Border? Relevant Laws and Considerations (LSB10283, Apr. 12, 2019):

Little federal case law addresses these questions. Although recent media articles discuss at least four occasions when past presidents have restricted operations at ports of entry on the southern border, those executive measures apparently did not
prompt legal challenges that required federal courts to assess the Executive’s authority for the measures.

From the summary of Congressional Subpoenas: Enforcing Executive Branch Compliance (R45653, Mar. 27, 2019):

Congress currently employs an ad hoc combination of methods to combat non-compliance with subpoenas. The two predominant methods rely on the authority and participation of another branch of government. First, the criminal contempt statute permits a single house of Congress to certify a contempt citation to the executive branch for the criminal prosecution of an individual who has willfully refused to comply with a committee subpoena. Once the contempt citation is received, any prosecution lies within the control of the executive branch. Second, Congress may try to enforce a subpoena by seeking a civil judgment declaring that the recipient is legally obligated to comply. This process of civil enforcement relies on the help of the courts to enforce congressional demands.

From the summary of Free Speech and the Regulation of Social Media Content (R45650, Mar. 27,2019):

Some have argued that Congress should step in to regulate social media sites. Government action regulating internet content would constitute state action that may implicate the First Amendment. In particular, social media providers may argue that government regulations impermissibly infringe on the providers’ own constitutional free speech rights. Legal commentators have argued that when social media platforms decide whether and how to post users’ content, these publication decisions are themselves protected under the First Amendment. There are few court decisions evaluating whether a social media site, by virtue of publishing, organizing, or even editing protected speech, is itself exercising free speech rights. Consequently, commentators have largely analyzed the question of whether the First Amendment protects a social media site’s publication decisions by analogy to other types of First Amendment cases.

From the summary of Congressional Participation in Litigation: Article III and Legislative Standing (R45636, Mar. 26, 2019):

Houses, committees, and Members of Congress periodically seek to initiate or participate in litigation to, among other purposes, advance their legislative objectives, argue that the Executive is violating their legislative prerogatives, or defend core institutional interests. However, the constitutionally based doctrine of “standing” — which requires a litigant seeking federal judicial relief to demonstrate (1) a concrete and particularized and actual or imminent injury in fact, (2) that is traceable to the allegedly unlawful actions of the opposing party and (3) that is redressable by a favorable judicial decision — may prevent legislators from pursuing litigation in federal court. The U.S. Supreme Court and the lower federal courts have issued several important opinions analyzing whether — and under what circumstances — a legislative entity has standing to seek relief.

From the summary of Arms Control and Nonproliferation: A Catalog of Treaties and Agreements (RL33865, Mar. 18, 2019):

Arms control and nonproliferation efforts are two of the tools that have occasionally been used to implement U.S. national security strategy. Although some believe these tools do little to restrain the behavior of U.S. adversaries, while doing too much to restrain U.S. military forces and operations, many other analysts see them as an effective means to promote transparency, ease military planning, limit forces, and protect against uncertainty and surprise. Arms control and nonproliferation efforts have produced formal treaties and agreements, informal arrangements, and cooperative threat reduction and monitoring mechanisms.

From the summary of Special Counsel Investigations: History, Authority, Appointment and Removal (R44857, Mar. 13, 2019):

The Constitution vests Congress with the legislative power, which includes authority to establish federal agencies and conduct oversight of those entities. Criminal investigations and prosecutions, however, are generally regarded as core executive
functions assigned to the executive branch. Because of the potential conflicts of interest that may arise when the executive branch investigates itself, there have often been calls for criminal investigations by prosecutors with independence from the executive branch.

In response, Congress and the U.S. Department of Justice (DOJ) have used both statutory and regulatory mechanisms to establish a process for such inquiries. These frameworks have aimed to balance the competing goals of independence and accountability with respect to inquiries of executive branch officials.

From Strategic Competition and Foreign Policy: What is “Political Warfare”? (IF 11127, Mar. 8, 2019):  “Political Warfare” is a term that has recently been reinvigorated by scholars of strategy; it describes the synchronized use of any aspect of national power short of overt conventional warfare — such as intelligence assets, alliance building, financial tools, diplomatic relations, to name a few — to achieve state objectives.

From the summary of Constitutional Authority Statements and the Powers of Congress: An Overview (R44729, Mar. 11, 2019):

On January 5, 2011, the House of Representatives adopted an amendment to House Rule XII to require that Members state the constitutional basis for Congress’s power to enact the proposed legislation when introducing a bill or joint resolution. (The amendment does not pertain to concurrent or simple resolutions). This Constitutional Authority Statement (CAS) rule, found at House Rule XII, clause 7(c), was subsequently adopted by every subsequent Congress.

A CAS is fundamentally a congressional interpretation of the Constitution, in that House Rule XII requires each Member introducing a piece of legislation to attach a statement that cites the power(s) that allows Congress to enact the legislation.

From the summary of The Congressional Review Act: Determining Which “Rules” Must Be Submitted to Congress (R45248, Mar. 6, 2019):

The Congressional Review Act (CRA) allows Congress to review certain types of federal agency actions that fall under the statutory category of “rules.” The CRA requires that agencies report their rules to Congress and provides special procedures under which Congress can consider legislation to overturn those rules. A joint resolution of disapproval will become effective once both houses of Congress pass a joint resolution and it is signed by the President, or if Congress overrides the President’s veto.

From the introduction to The Emoluments Clauses of the U.S. Constitution (IF11086, Jan. 30, 2019):

Recent litigation involving President Trump has raised a number of legal issues concerning formerly obscure constitutional provisions that prohibit the acceptance or receipt of “emoluments” in certain circumstances. This In Focus provides an overview of these constitutional provisions, highlighting several unsettled legal areas concerning their meaning and scope, and reviewing the status of ongoing litigation against President Trump based on alleged violations of the Emoluments Clauses.

From the summary of Congress’s Authority to Influence and Control Executive Branch Agencies (R45442, Dec. 19, 2018):

The most potent tools of congressional control over agencies, including those addressing the structuring, empowering, regulating, and funding of agencies, typically require enactment of legislation. Such legislation must comport with constitutional requirements related to bicameralism (i.e., it must be approved by both houses of Congress) and presentment (i.e., it must be presented to the President for signature). The constitutional process to enact effective legislation requires the support of the House, Senate, and the President, unless the support in both houses is sufficient to override the President’s veto.

From the introduction to The First Step Act of 2018: An Overview (R45558, Mar. 4, 2019): “On December 21, 2018, President Trump signed into law the First Step Act of 2018 (P.L. 115-391). The act was the culmination of several years of congressional debate about what Congress might do to reduce the size of the federal prison population while also creating mechanisms to maintain public safety. This report provides an overview of the provisions of the act.”
