Hello. Here's your morning briefing:
Trump-Russia probe: Grand jury assembled
Could there be criminal charges over claims that Russia meddled in last year's US presidential election? The Reuters news agency reports that Robert Mueller, the special counsel investigating the allegations, has assembled a grand jury - a panel of ordinary citizens which decides if a case is strong enough to issue indictments for a criminal trial.
It's also reported that the jury has issued subpoenas - legal writs to obtain documents or compel witnesses to testify under oath - over a meeting last June between President Donald Trump's son, Donald Trump Junior, and a Russian lawyer.
Russia denies any involvement in the election and, in a rally on Thursday, the US president called any allegations that his campaign team had colluded with Moscow a "hoax" and a "total fabrication".

By Martin Bashir, religious affairs correspondent
As he enters a mud-walled building, which cannot be more than 12 feet (3.7m) square and is home to a family of five, the Archbishop of Canterbury asks if it can withstand rain? "No," says the father, who points to the single matted carpet that is still damp from the previous day's rainfall. "This is dreadful," is the archbishop's quiet response.
