WASHINGTON, D.C. - The nation continues to mourn the loss of former President George H.W. Bush.

Now, we’re learning more about the late President’s funeral and how the public can pay their respects. That tops the list of the Three Big Things we’re following in the Washington newsroom this week.

Bush funeral and Capitol services

Bush’s funeral is scheduled Wednesday at the Washington National Cathedral and it’s expected that thousands of people will pay their respects starting Monday night and into Tuesday when the late president is lain in state at the U.S. Capitol.

If you plan on attending the viewing to pay respects to the 41st President, there are several security guidelines in place, according to the U.S. Capitol Police.

“Please note:  No flowers, sealed envelopes, or other offerings/tokens will be allowed into the U.S. Capitol or Capitol Visitor Center,” a statement on the USCP website reads. More information about security measures for the Capitol viewing service can be found here.

President Trump designated Wednesday as a national day of mourning, and that has shifted the schedule for some other events on Capitol Hill.

The U.S. Capitol Christmas Tree lighting ceremony scheduled for Wednesday is now scheduled for Thursday on the Capitol’s west lawn. The tree arrived in Washington from Oregon’s Willamette National Forest Nov. 26 it will officially be lit during a ceremony now scheduled for Thursday at 5p.m.

Looming government shutdown & border wall funding

When it comes to politics itself, all eyes are on Friday’s deadline for a potential government shutdown. The big issue still is funding for President Trump’s border wall. The president wants $5 billion for the project. However, Senate Democrats will offer just $1.6 billion.

A stop-gap measure to avoid a shutdown could be implemented this week, according to reports. However, House Republican leaders have postponed votes this week due to the Bush funeral services. The Senate is still scheduled to vote late Wednesday.

Congress previously averted a shutdown by passing a spending plan in late September, just weeks before the midterm election.
