Donald Trump Jr.'s lengthy narrative of his family's company history has a theme

From CNN's Lauren del Valle, Kara Scannell and Jeremy Herb

In Donald Trump Jr.’s narrative in court Monday, his father has taken over dilapidated buildings and properties and used his skills as a "visionary" to turn them all into one of the best in the city, the country and in some cases, the world.

When the Trump Organization took over the Trump Park Avenue building, Donald Trump Jr. oversaw the renovation project and testified Trump Org. created a space with one of the highest prices per square foot in the city at the time, he said.

Trump Jr. referred to the additions they added to the top of the Park Avenue building as being like the Louvre with glass cubes added to provide more light.

The Trump International Golf Club in West Palm Beach, Florida, was swampland before his father took it over. "No one for decades had seen any value in it," Trump Jr. said, and Donald Trump turned it into "one of the finest golf clubs in the world."

Trump Jr. said that when the Trump Org. developed the Trump National Golf Club Los Angeles, his father “noticed a crown jewel and had to have it and turn it into something special."

Trump attorney Cliff Robert has spent the morning walking Trump Jr. through nearly all of the Trump properties to help build the narrative, including some of the properties that the New York attorney general alleges were fraudulently inflated in value on Trump’s financial statements.

During his questioning by the attorney general’s office earlier in the trial, Trump Jr. claimed he wasn’t familiar with the valuations of the properties included on the financial statements.

The New York attorney general's office will have the chance to cross-examine Trump Jr. again, and could raise his awareness of the value of the assets in question in this case.
