President Donald J. Trump speaks with his coronavirus task force in response to the COVID-19 coronavirus pandemic during a briefing in the James S. Brady Press Briefing Room at the White House on Tuesday, March 17, 2020 in Washington, DC.

The Trump administration's proposed stimulus package to combat economic fallout from the coronavirus pandemic will include two rounds of direct payments to taxpayers totaling $500 billion, according to a document obtained by NBC.

The White House hopes to send out its first round of checks on April 6, and the second on May 18. It will base payments on income level and family size, according to the document.

Beyond direct payments, the government is looking to set aside $50 billion for the ailing airline industry, as well as $150 billion for "other distressed sectors." It was not immediately clear which industries would be covered, but the tourism and hotel industries are among those that have also asked the government for relief.
