now in a recession.
Overall, the unemployment rate fell to 3.5 percent.
That is the lowest it has been in 50 years.

ADIL ABDUL-MAHDI, ®MD-UL¯Iraqi Prime Minister (through translator): Your demands in countering

face masks.
Thousands of demonstrators turned out, wearing masks.
They protested into the night, vandalizing storefronts, setting fires at subway stations
and defying the city's chief executive.
CARRIE LAM, Hong Kong Chief Executive: If there's no violence, if there's no protests,
we do not need to have all these instruments with us in order to deal with this violence.
Of course, if the situation worsens -- I suppose that's your question -- then, as a responsible
government, we will continue to have to identify other means that we could tackle the situation.
JUDY WOODRUFF: The protesters wear masks to avoid being identified and punished.
But, as of Saturday, violations could mean a year in jail.

any and all communications.
WILLIAM BARR, U.S. Attorney General: We would be happy if the companies providing the encryption
keep the keys.
What we are asking is some responsible party have the keys, so that when we can demonstrate
a lawful basis, probable cause that crimes are being committed, we can gain access to
that evidence.

systems.
