Another shutdown for parts of the federal government is expected this weekend. Funding for the Department of Homeland Security is set to expire Saturday as lawmakers debate new restrictions on President Donald Trump's immigration enforcement agenda. The White House has been negotiating with the Democrats, but the two sides failed to reach a deal by the deadline. Unlike the record 43-day shutdown last fall, the closures will be narrowly confined, as only agencies that are part of Homeland Security will be affected. Still some federal workers could begin to miss paychecks and services like airport screening could be affected if the shutdown drags on for weeks.

Low-value imports are no longer eligible to enter the U.S. duty-free. An order signed by President Donald Trump eliminated a widely used customs exemption for international shipments worth $800 or less as of 12:01 a.m. Eastern time on Friday. The national postal services of more than 30 countries have temporarily suspended sending some or most U.S.-bound packages because of the change. They say they didn't have enough time or information to prepare for collecting the new import taxes on small parcels. Logistics experts say that in addition to bringing new costs for sellers and buyers, the end of the "de minimis" exception is likely to delay orders.
