US President Donald Trump has met with the heads of 18 US technology companies including Apple, Amazon.com and Microsoft, seeking their help to make the government's computing systems more efficient.
The White House wants to update government information technology systems, cut costs, eliminate waste and improve service.
Trump cited estimates that the government could save up to $1 trillion over 10 years through such measures.
"Our goal is to lead a sweeping transformation of the federal government's technology that will deliver dramatically better services for citizens," Trump said. "Government needs to catch up with the technology revolution."
The executives are part of the so-called American Technology Council that Trump formed in May to support efforts to modernise the US government.
"The US should have the most modern government in the world. Today it doesn't," Apple's chief executive Officer Tim Cook said
Amazon CEO Jeff Bezos said he wanted the Trump administration to make use of commercially available technologies, worker retraining, machine learning and artificial intelligence.
Before meeting with Trump, the CEOs met in 10 small group sessions with Vice President Mike Pence, Treasury Secretary Steve Mnuchin and Commerce Secretary Wilbur Ross.
Jared Kushner, Trump's son-in-law and adviser, said the administration wanted to "unleash the creativity of the private sector to provide citizen services in a way that has never happened before."
He said the administration was scrapping unneeded regulations for government computing systems, such as a rule on preventing Y2K issues.
Most of the US government's 6,100 data centres can be consolidated and moved to a cloud-based storage system.
The White House is seeking to shrink government, reduce the federal workforce and eliminate regulations.
Trump in March signed an order to overhaul the federal government and tapped Kushner to lead a White House Office of American Innovation to leverage business ideas and potentially privatise some government functions.
Many of the tech executives are eager to get White House help in dealing with regulatory and other policy issues such as visas for highly skilled workers.
Others attending include Alphabet executive chairman Eric Schmidt, venture capital firm Kleiner Perkins Chairman John Doerr and the CEOs of Microsoft, IBM, Intel, Qualcomm, Oracle and Adobe Systems
Facebook CEO Mark Zuckerberg was invited but could not attend because of a conflict, the company said.
A 2016 US Government Accountability Office report estimated the government spent more than $80 billion in IT annually, excluding classified operations.
In 2015, the US government made at least 7,000 separate IT investments and some agencies were using systems that had components at least 50 years old. "This structure is unsustainable," Kushner said.
Following Trump's June 1 decision to withdraw from the Paris climate accords, Tesla CEO Elon Musk and Walt Disney CEO Robert Iger stepped down from White House advisory panels.
White House officials said the dispute had little impact and that they had to turn away tech leaders from yesterday's event because of lack of space.
