The US House of Representatives will not reconvene next week following a revolt from lawmakers who complained that it was too soon to return.
On Monday, members were told to return to the Democratic-controlled chamber.
However, House Majority Leader Steny Hoyer said on Tuesday the plan was scrapped after consulting the House doctor.
The volte-face came as the confirmed number of US Covid-19 cases passed 1m.
Americans fear COVID-19 second wave more than economic collapse
The Republican-controlled Senate still plans to return on 4 May.
