Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, shares his perspective on US politics:

What was the biggest takeaway from the first January 6th hearing?

The House Committee investigating the January 6th riot at the Capitol hosted its first hearing last night. And while a major focus of the committee is making the case for the criminal culpability of former President, Donald Trump, for his role in instigating the riots, much of the facts revealed last night were already well known through leaks from the committee and are unlikely to change any minds for either supporters or detractors of the former president.

The committee also spent significant resources uncovering a connection between two nationalist groups, the Proud Boys and the Oath Keepers, in their role in deliberately stoking violence that day. The committee showed video evidence that group members coordinated in advance to attack the Capitol and disrupt the certification of a completely valid election. And they were egged on by Donald Trump's appearance at the White House that morning. The existence of these nationalist groups and their ability to organize online is going to be an ongoing challenge in the United States, which is starting to see elevated levels of political division and outright political violence.
