>> reporter: we have been told
and there have been spotted
protesters are inside the
capitol building.
scores of protesters, there have
been witnessed outside the
senate -- just off the senate
floor, the second floor of the
capitol.
an alert just went out to all
congressional staff as well as
everybody in the capitol
building, urging people to move
insire their offices, telling
them to take emergency equipment
with them, stay away from
external doors and winds.
it says if you're in a public
space, find a place to high,
seek cover, remain quiet,
silence electronics.
one of you're in a safe
location, tell your superiors.
no one will be permitted to
exercise or exit the capitol
building until directed by the
u.s. capitol police.
this alert also says if you're
in a building outside of the
affected area, remain clear of
the police activity, and await
further direction.
