White House press secretary Sean Spicer said Monday that it would be "inappropriate" for the administration to comment on where the Trump family's eponymous companies manufacture their wares amid questions related to President Trump's push this week to highlight companies that make goods in the U.S.

"With respect to his own companies, obviously it's inappropriate to discuss how anything would affect their own companies," Spicer told reporters at the White House on Monday.

The fashion line founded by Trump's daughter, Ivanka, manufactures products overseas in countries including China and Bangladesh. A number of Trump-branded products have come from overseas factories as well, an issue that became a line of attack against Trump during the presidential race.

Spicer said in certain cases "supply chains or scalability" necessary to the operation of companies like Trump's might not be available in the U.S.

"There's certain industries that we don't do as much anymore," Spicer said. "There's certain things that we may not have the capacity to do here."

The White House has planned a series of events this week showcasing the president's push to encourage corporations to make their products in the U.S.

"Made in America Week" kicked off Monday with an event at the White House during which companies from all 50 states displayed goods that they produced domestically.

"Obviously we want to create an environment in which more things are made here," Spicer said.

The president has pursued a number of pro-growth, anti-regulatory policies aimed at growing the country's manufacturing sector.

Slowing the pace of outsourcing and recovering jobs that had moved overseas due to unfavorable trade agreements were two of the biggest promises Trump made during the presidential race.
