By Kevin Liptak, CNN(CNN) — One of the nation’s premier historic preservation groups on Tuesday urged the Trump administration to pause demolition of the White House East Wing, which excavators began tearing into this week to make way for President Donald Trump’s planned ballroom. The work continued Tuesday as the excavators tore further into the building, the sounds of rhythmic pounding and occasional crashing drifting across the 18-acre White House campus. That’s music to my ears; I love that sound,” Trump told a group of Republican senators having lunch in the Rose Garden. The structure being demolished includes the suite of offices traditionally used by the first lady, as well as space for White House calligraphers, certain military aides, and the social secretary. The National Trust for Historic Preservation is not the only group to call for a more rigorous review of the ballroom project.
