As you might have guessed, as a result of the president’s attendance, security on the Mall has been ramped up:

Security is extremely tight at @March_for_Life. — Samantha Sullivan (@SamSullivan) January 24, 2020

Extra security in place for this year’s #MarchForLife. President Trump will be the first president to attend the annual event pic.twitter.com/FYUMSiNED6 — Cory Smith (@CoryNBC) January 24, 2020

Increased security/limited entrances to #MarchForLife: The National Mall is entirely fenced off from 7th Street to 14th St., meaning all participants in the March for Life must enter on 14th. — Michelle Boorstein (@mboorstein) January 24, 2020

People are already making their way into DC for the 47th annual March For Life, which starts at noon.

Reminder: the Smithsonian Metro Station is closer for security reasons, due to its proximity to the event. pic.twitter.com/gs2dd9zPBd — Heather Graf (@ABC7HeatherGraf) January 24, 2020

There will be ONE security entrance for today's #MarchForLife on 14th St at the Mall. Everyone will have to go through metal detectors at that ONE entrance. President Trump will speak just after 12pm — Steve Chenevey FOX5 (@stevechenevey) January 24, 2020

Enter security on the 14th street side near the African American museum to attend @realDonaldTrump speech at @March_for_Life – plenty of security checkpoints, no lines at this point — Charlie Spiering (@charliespiering) January 24, 2020

We’ll post video of the president’s address at the March for Life rally after the speech concludes.
