How President Donald Trump parties Friday night

WASHINGTON – President Donald Trump and First Lady Melania Trump danced to Frank Sinatra's "My Way" during the Liberty Ball  -- one of the three parties they would attend on Friday night.

Fashionistas who admired the First Lady's Ralph Lauren powder-blue cashmere dress during the day were pleased to see her in a vanilla crepe off-the-shoulder gown by Hervé Pierre, a French designer who has lived in the U.S. for decades. 

Before the dance, the 45th president of the United States delivered a short speech that was far from his inaugural 16-minute address at the West Front of the U.S. Capitol.

"This is a movement and now the work begins. We love you," Trump said. "We're going to be working for you and we're going to produce results."

Protesters frightened well-dressed Trump supporters, as they ventured to the new president's inaugural balls. Police briefly ordered ball goers to remain inside their hotel as they worked to contain advancing protesters.

Before the parties, Trump stepped into the Oval Office and signed his first executive order in a process to repeal "Obamacare." Vice President Mike Pence administered the oath of office to Defense Secretary James Mattis and Homeland Security Secretary John Kelly. 

Trump also signed a proclamation declaring a national day of patriotism, according to a tweet from White House spokesman Sean Spicer. The Department of Housing and Urban Development suspended a planned reduction of mortgage insurance premium rates.

Pence and his wife, Karen Pence, joined Trump and his family on stage. Ivanka Trump remained faithful to Carolina Herrera this week. She wore a sparkling v-neck princess gown with sheer sleeves. 

It was a long day for Trump, the oldest person to be sworn in as president. The third ball was the more exclusive A Salute To Our Armed Services Ball at the National Building Museum. 

The night's performers included, The Rockettes, The Piano Guys, Tony Orlando, Josh Weathers, the '60s R&B and soul duo Sam & Dave.
