As the government shutdown enters its fourth week, President Donald Trump welcomed Senate Republicans for lunch in the newly renovated White House Rose Garden Club.

The gathering wasn't organized for urgent talks on how to end the shutdown, but rather as a celebratory display of unity as they refuse to negotiate on Democratic demands for health care funds.

"Today I'm calling on every Senate Democrat to stop the madness, to let our country get back in the greatest moment in the history of our country in terms of wealth, in terms of, job creation and in terms of investment coming in," Trump said.

Dozens of GOP senators and senior administration officials were in attendance on the patio, which was decked out with yellow umbrella-covered tables for the occasion.

Cheeseburgers and fries are on the menu, as well as “Rose Garden chocolates” for dessert.

Trump hailed the renovations as a "labor of love."

"You know, we took over a building that was not properly taken care of. It just wasn't. It's a very special building. And we are taking care of it," he said.

The president also reveled in the construction of his 90-thousand square foot ballroom, which started this week.

"You probably hear the beautiful sound of construction to the back. You hear that sound? Oh, that's music to my ears. I love that sound," Trump said.

"When I hear that sound, it reminds me of money. In this case, it reminds me of a lack of money because I'm paying for it. So it's the opposite," he said.
