This is shaping up to be the second straight split-screen day in American politics, the continuation of two amazing storylines: a public reckoning for a Silicon Valley titan and the high-stakes investigation of a trusted confidant of President Trump.
For Mark Zuckerberg, the impresario of Facebook, there's probably relief this week's spotlight isn't only being shined on him.
FACEBOOK'S CEO DOESN'T GET A 'LIKE' FROM LAWMAKERS
If Zuckerberg thought he'd get the benefit of the doubt on Capitol Hill after saying he's sorry, he was wrong.
For several hours, Democratic and Republican senators alike grilled the tech leader over Facebook's actions in the 2016 election season and its overall approach to the privacy of user data.
"Let me just cut to the chase," Sen. Bill Nelson (D-Fla.) said to Zuckerberg on Tuesday. "If you and other social media companies do not get your act in order, none of us are going to have any privacy anymore."
Zuckerberg's appearance had the markings of old guard versus new guard, especially with some questions from senators who didn't seem to have a lot of personal experience with Facebook.
We're tracking his testimony to the House Energy and Commerce Committee this morning on our Essential Washington news feed.
THE LAWYER, THE INVESTIGATION, THE GOP BLOWBACK
The other side of the political split screen may squeeze the Facebook discussion out of the picture by week's end. With federal prosecutors raiding the office of Trump's personal attorney Michael Cohen and more angst via Twitter from the president, the nation's Republican leadership is in a pickle.
As Cathleen Decker writes, congressional Republicans are facing tough questions about whether they should embrace protection of Robert S. Mueller III, the special counsel investigating Russian activity in the presidential election.
Meanwhile, there's the attorney in the crosshairs. Cohen became close to Trump because of his die-hard loyalty and his willingness to do just about anything to protect the developer-turned-president's reputation. That loyalty is now being put to the test.
NATIONAL POLITICS LIGHTNING ROUND
-- Tensions, too, are mounting over what the Trump administration will do over reports of the recent deadly chemical attack in Syria. "Russian hands," U.N. Ambassador Nikki Haley said on Monday, "are all covered in the blood of Syrian children." On Wednesday, Trump tweeted that missiles to Syria "will be coming."
-- As Pentagon planners scramble to prepare for a possible U.S. retaliatory military response in Syria, one danger has sparked special concern — whether airstrikes could inadvertently kill Russian soldiers in Syria and escalate the regional war. The situation has left Syrian troops on high alert.
-- All of it was enough to convince Trump to skip this week's visit to Peru and Colombia, which was to be highlighted by the Summit of the Americas gathering of international leaders in Peru.
-- This week would have been an especially raw time for President Trump to visit Latin America. But canceling the trip could leave the region even angrier.
-- A day after Trump called aspects of the U.S.-China trade relationship "stupid," his Chinese counterpart tried a different strategy. President Xi Jinping promised to slash auto tariffs and further open the country's markets to imports.
-- Mick Mulvaney's overhaul of the Consumer Financial Protection Bureau is so extensive it now could include revising the agency's name.
-- Trump devoted his weekly address over the weekend to an attack on California's "sanctuary" laws, arguing without evidence that the state had made itself "a border-free zone where thousands of criminal aliens can roam free."

BUILD THE WATER TUNNELS, SAYS KEY REGIONAL AGENCY
Southern California's biggest water agency has voted to shoulder most of the cost of a sweeping plan to rebuild the intersection of the state's vast waterworks, committing nearly $11 billion to the project.
Tuesday's vote was a major victory for Gov. Jerry Brown, who lobbied the Metropolitan Water District to back his plans for twin water tunnels beneath the Sacramento-San Joaquin delta.
BECERRA SUES OVER ANTI-POLLUTION RULE
California Atty. Gen. Xavier Becerra filed a lawsuit Tuesday against the Trump administration to challenge the repeal of a policy that requires major sources of air pollutants, including oil refineries, to reduce their emissions.
Becerra's action, on behalf of the state Air Resources Board, targets a policy change by the U.S. Environmental Protection Agency that would no longer require major polluters to install and operate equipment to permanently minimize the release of hazardous substances.
-- Becerra is appealing a San Diego federal judge's ruling allowing construction of Trump's border wall.
