Both chambers of the US Congress convened for only a few minutes late on Thursday, but took no steps to end a partial federal government shutdown before adjourning until next week.
Showing little sense of urgency over the shutdown, now in its sixth day, the Senate and the House of Representatives did nothing to restore funding for the roughly 20 percent of the government affected.
The shutdown was on track to continue into next week and possibly drag on well into January.
The shutdown was triggered by Republican President Donald Trump's demand, largely opposed by Democrats and some lawmakers within his own party, that US taxpayers provide $5 billion for a wall he wants to build along the US-Mexico border.
Trump wants the money to be included in spending measures that Congress must pass to restore funding to several government agencies, including the departments of Homeland Security, Justice, Agriculture and Commerce.
