Speaking of confrontation: The Republican-led Senate Intelligence Committee has subpoenaed Donald Trump Jr.

• The subpoena is to answer questions about his previous testimony before Senate investigators in relation to the Russia investigation, sources with direct knowledge told Axios' Jonathan Swan, Alayna Treene and David Nather.

Why it matters: It's the first congressional subpoena — that we know about — of one of President Trump's children.

• The subpoena sets up an unprecedented fight in the Trump era: A Republican committee chair pit against the Republican president's eldest son.
• It's also a sign that the Russia investigations in Congress aren't over despite the conclusion of special counsel Robert Mueller's probe and despite Senate Majority Leader Mitch McConnell saying it's time to move on from the Russia probe.
• A Senate Intelligence Committee spokesperson told Axios: "We do not discuss the details of witness engagements with the Committee. Throughout the investigation, the Committee has reserved the right to recall witnesses for additional testimony as needed, as every witness and witness counsel has been made aware."

Between the lines: Mueller, whose investigation did not find a conspiracy between the Trump campaign and Russia, did not indict Trump Jr., despite speculation that he would.

• Unlike many congressional investigations in the Trump era, the Senate Intelligence probe — led by Republican chairman Richard Burr and Democratic vice chair Mark Warner — has been largely bipartisan.
• The fact that they're subpoenaing Trump Jr. is a strong signal that he declined a request to appear before the committee again.

"America’s oldest performing arts group is looking for a child who was literally wowed by a recent classical music concert," the AP reports.

• "The Handel & Haydn Society had just finished its rendition of Mozart’s 'Masonic Funeral' at Boston’s Symphony Hall on Sunday when a youngster blurted out loudly: 'WOW!'"
• "The crowd can be heard bursting first into laughter and then rousing applause for the child."
• "Now the organization founded in 1815 has mounted a search for the kid it’s calling the 'Wow Child' — not to reprimand him or her, but to offer a chance to meet the conductor and hear the orchestra again as a guest of honor.'"
