• The White House hosted some prominent entertainers on Thursday to celebrate President Donald Trump signing the Music Modernization Act, which ensures the rights of songwriters in the digital era.
  • Kid Rock, The Beach Boys cofounder Mike Love, country singers John Rich and Craig Morgan, and Christian rock band MercyMe were among the musicians in attendance.
  • Later on, rapper Kanye West and retired NFL player Jim Brown joined Trump for a working lunch to discuss a handful of issues.

The White House welcomed a star-studded group of guests on Thursday to attend President Donald Trump's signing of the Music Modernization Act, and Trump's working lunch. The president also had a sit-down in the Oval Office with rapper Kanye West and former NFL player Jim Brown.

The Music Modernization Act, named for retiring Rep. Bob Goodlatte of Virginia and retiring Sen. Orrin Hatch of Utah, who is also a songwriter, secured widespread bipartisan support.

The Act updates current music licensing law to enable songwriters to be adequately compensated from revenues originating from online music streaming, allow producers to earn royalties from songs played over online and satellite radio, and ensure royalty payments for the writers and performers of songs written before 1972.

Musicians including Kid Rock, The Beach Boys cofounder Mike Love, and Christian rock group MercyMe attended the bill signing. NFL legend Jim Brown and Kanye West later joined Trump in the Oval Office for a working lunch and a televised meeting with reporters. West previously met with Trump shortly after his election in 2016

Here are all the celebrities who appeared at the White House on Thursday:

Kid Rock

Robert James Ritchie, better known as the musician Kid Rock, attended the signing for the Music Modernization Act at the White House in his signature rockstar garb and sunglasses.

Kid Rock himself is one of Trump's most prominent supporters in the entertainment community, and even floated a run for Senate in Michigan, although he later revealed it was a promotional tactic for his most recent album.

Sam Moore

Trump welcomed Sam Moore, a Rock & Roll Hall of Famer best known as one-half of the soul and R&B duo Sam & Dave, to the White House and wished him a happy 83rd birthday, which he celebrates October 12.

Mike Love

Mike Love, the Grammy Award-winning cofounder of The Beach Boys who also holds a spot in the Rock & Roll Hall of Fame, also appeared alongside Trump for the bill signing.

Jeff "Skunk" Baxter

Jeff "Skunk" Baxter, who had a long career in music as a guitarist for bands including Steely Dan and the Doobie Brothers during the 1970s and 1980s, and later toured with artists including Sheryl Crow, Dolly Parton, and Rod Stewart in the 1990s, also attended the signing.

More recently, however, Baxter has been better known for his work as a missile defense expert and consultant.

After gaining expertise in the topic and obtaining several security clearances in the 1990s, Baxter was appointed to the

John Rich

John Rich, who appeared to celebrate the bill's signing, is not only a longtime country singer-songwriter who preformed as a bass guitarist in the band Lonestar and as half of the Big & Rich duo, but a 2011 "Celebrity Apprentice" contestant.

"He happened to win the Apprentice, but we won't even get into that," Trump, who hosted "The Apprentice," joked. "I know him better than anybody. I said 'you're fired' to everybody except John Rich ... he's good under pressure which is very nice."

Rich took to Twitter to celebrate the bill signing, writing, "And the #MusicModernizationAct is now American law! Thank you to the Senate, House, and [Trump] for unanimously passing this bill. The songwriters thank you!"

Christian rock band MercyMe

The contemporary Christian rock band MercyMe, pictured here at the 2018 Grammy Awards, also appeared at the White House to commemorate the bill signing.

The band has previously preformed at the 2017 annual White House prayer breakfast.

Craig Morgan

Country artist Craig Morgan also joined Trump and fellow artists to celebrate the bill's signing.

Kanye West

Kanye West, who has become a controversial and polarizing figure in the entertainment industry and in the African-American community over his vocal support of Trump, sat down with Trump and retired NFL player Jim Brown in the Oval Office after the bill signing.

After Trump, West, and Brown discussed issues including urban redevelopment, economic opportunity for African-Americans, and gang violence over lunch, their televised Oval Office sit-down took a different theme when West launched into a freewheeling 10-minute soliloquy.

"He can speak for me anytime he wants," Trump said of West. "He's a smart cookie. He gets it."

Former NFL player Jim Brown

Joining Trump and West for their Oval Office sit-down was retired NFL player Jim Brown, who devoted much of his resources as a high-profile athlete to advocating for civil rights and spearheading initatives to help African-Americans start their own businesses in the 1960s.

After the meeting, he took questions from reporters outside the White House and offered his thoughts on NFL players taking a knee during the national anthem to protest police brutality and systematic racism.
