The US Senate passed a bill to fund most of the Department of Homeland Security (DHS), potentially ending a lengthy partial government shutdown.
The legislative action was precipitated by severe airport delays, with TSA checkpoint wait times of 5-7 hours due to workers calling off work after not being paid for about five weeks.
The proposed funding excludes ICE (Immigration and Customs Enforcement) and Border Patrol, which are noted as the two most controversial components and will remain subject to separate negotiation.
The bill represents a sudden reversal for Republicans in Congress.
This Senate vote is only a preliminary step; the bill must still pass the House of Representatives and then be signed by President Donald Trump to become law.
The overall process is described as "tenuous" and could still take "several more days, if not a couple of weeks."
A supporting political factor is that President Trump publicly called for TSA agents to be paid the day before the Senate vote.
The core market implication is the potential resolution of a disruption (airport delays) caused by the shutdown, but significant legislative and political hurdles remain.
