Syndicated columnist Charles Krauthammer said President Trump's meeting with several union leaders was a "great act of political larceny" to the Democrats' detriment.

Trump met with Laborers' boss Terry O'Sullivan, Building Trade Union head Sean McGarvey, Carpenters' Union president Mark McManus and other leaders in the Oval Office.

Afterward, the union leaders assembled outside the White House to issue a brief statement to the press.

Krauthammer called Trump's first business day in office "very organized and disciplined."

"That scene of him with union leaders was a great act of political larceny," Krauthammer said, noting that union workers were a major Democratic constituency that he "stole" in order to get elected in 2016.

"As long as he nurtures [the relationship with unions], he has a leg up on the Democrats," he said.
