And then:A school in the US state of New Jersey is under fire for an assignment that asked children aged 10-11 to create posters depicting slave auctions.Some parents reacted angrily when they attended the school and saw the posters hanging in a hallway.
The principal apologised for any pain or offence caused.
District officials said children needed to learn about the "uglier parts of our past", but accepted the posters should not have been hung without context.
The assignment had been set by the South Mountain Elementary School in South Orange, near Newark.
Mexican Foreign Secretary Luis Videgaray met senior White House aides without the State Department's knowledge, according to an official.State Department acting spokesman Mark Toner said he was "unaware" the foreign minister was in Washington.
The secretary of state typically receives foreign diplomats during visits to the nation's capital.
The disconnect comes amid reports that the State Department has been sidelined in matters of foreign policy.
"We'll take that and get back to you. I was unaware that he was - the foreign minister was in town," Mr Toner said at a news conference on Thursday.
