• Good morning! Congress returns to town today facing intense pressure to solve their decades-long failure to institute any gun-control measures. Governors gathered in Washington last week warned of the perils of inaction. And President Trump claimed that he told the National Rifle Association that it needs to get busy helping to craft some gun-control legislation, including considering raising the age for purchase of semiautomatic weapons to 21. “If past is prologue,” the New York Times reports, “Congress will do nothing.”

• President Trump’s lawyers are examining ways that he might testify before Special Counsel Robert Mueller, including limiting questions to specified topics that won’t test his at-times-limited memory or lure him into a perjury trap, the Wall Street Journal reports. But while the president and his advisers claim to be unworried by the inquiry, because none of the charges so far have implicated Trump, the flurry of recent indictments and guilty pleas appear to be heading toward a larger target, according to the New York Times.

• Three big cases will be argued before the Supreme Court this week. On Monday, it’s Janus v. American Federation, and the issue is whether unions can charge “agency fees” to non-members in order to cover the cost of collective bargaining. The Court previously ruled that unions can do so, but Mark Janus has claimed that his union is violating his free speech rights because it supports issues that he doesn’t, even if the money isn’t used for overtly political purposes. The last time the Court considered such a case, after the death of Justice Scalia, it deadlocked 4-4. The addition of Neil Gorsuch makes likely that the Court will rule against the unions, which would cost them millions of dollars and thwart their political activities.

• On Tuesday, the Supreme Court hears US v. Microsoft, where the issue is whether an email service provider must comply with a US subpoena for emails that are stored offshore. The case centers on the Stored Communications Act, passed by Congress in 1986 – before email use was widespread and before the consumer Internet existed. And on Wednesday, it’s Minnesota Voters Alliance v. Mansky, which turns on whether a state can bar a voter from wearing clothes with a political message at a polling place.

• Federal Reserve Chairman Jerome Powell will make his first appearance in the chairman’s role before two congressional committees this week, offering the traditional semiannual testimony on monetary policy and the state of the economy on Tuesday to the House Committee on Financial Services and on Thursday to the Senate Banking Committee. The hearings come just weeks after fears of higher interest rates shook the stock market with multiple 1,000-point losses. Also Tuesday, the Brookings Institution hosts “A Fed Duet: Janet Yellen in conversation with Ben Bernanke.”

• Secretary of State Rex Tillerson will give the lowdown on the State Department’s 2019 budget request, and his much-anticipated but publicly vague plans to redesign the cabinet agency, at a budget hearing before the Senate Foreign Relations Committee on Wednesday. According to Politico, the blueprint has gone from wrecking ball to hammer-and-chisel, but it still has the striped-pants fraternity on edge.

• When the White House released an outline of its $1.5 trillion infrastructure plan earlier this month, the reviews were essentially … meh. The federal government would contribute only $200 million to the effort, with the remainder coming from public-private partnerships and state and local contributions. Still, it’s a start on a much-needed public works undertaking, and on Thursday the Senate Environment and Public Works Committee will probe “The Administration’s Framework for Rebuilding Infrastructure in America.”

• From bridges and roads to digital systems, many of the concerns about infrastructure revolve about the safety and security of networks, real and virtual. Also on Thursday, the Senate Energy and Natural Resources will take a hard look at “Cybersecurity in Our Nation’s Critical Energy Infrastructure.”

• Two more Congressional committees will mull what to do about opioids this week. On Tuesday, the Senate HELP Committee looks at “The Opioid Crisis: The Role of Technology and Data in Preventing and Treating Addiction,” while on Wednesday, the House E&C’s Subcommittee on Health looks at “Combatting the Opioid Crisis: Helping Communities Balance Enforcement and Patient Safety.” And on Thursday, it’s the US Chamber of Commerce hosting “Combatting the Opioid Crisis: From Communities to the Capital.”

• Even guys who live in relatively modest houses in Omaha got some benefit from the Trump Administration’s overhaul of the tax code. Take Warren Buffett, for example, whose Berkshire Hathaway enjoyed a $29 billion windfall from the revamping of the corporate income tax. That’s not that far off from that public-school secretary whose weekly paycheck soared by $1.50, is it?
