The upcoming US mid-term elections on 6 November will help define the rest of Donald Trump's presidency.

Americans will vote for members of both chambers of Congress, as well as for governors in 36 out of 50 states.

Between now and then, we'll bring you updates and all the best analysis every weekday in this round-up.

Today we look at the southern border, a special hotline and a bad day at the office for self-declared presidential hopeful Michael Avenatti.

One key issue

Reports emerged in US media overnight suggesting President Trump is considering closing the country's southern border using an executive order.

The move would bar migrants, including asylum seekers, from entering the country through Mexico.

It follows days of tweets by the President agitating over a caravan of Central American immigrants progressing north toward the US.

Mr Trump has tied the issue to the upcoming mid-terms, despite the group still being more than 1,000 miles and weeks away on foot.

Strong action on the border is likely to play well with Mr Trump's anti-immigration base - who elected him with famously tough rhetoric about the US-Mexico frontier.

According to the New York Times, Mr Trump could announce the closure early next week, invoking national security concerns, as he did with other travel bans.

Defence Secretary James Mattis is also expected to deploy around 800 troops to the US-Mexico border to help stop the migrant group.

One voter hotline

Democrats in Georgia have launched a special hotline to help answer questions from confused voters.

The call-centre, dubbed a voter protection "war room" by CNN, was set-up to help in a race that has been dominated by allegations of voter suppression.

Georgia Secretary of State Brian Kemp is neck-and-neck against former state representative Stacey Abrams - who hopes to become the country's first African-American female governor.

Earlier in the race, a bombshell Associated Press report said that 53,000 registrations (70% of which were from black voters) have been held up by Mr Kemp's office over technicalities.

Ms Abrams has accused her opponent of attempting voter suppression, saying his "pattern of behaviour" is eroding public trust in the system.

Mother Jones went behind the scenes at the hotline office - where 180 volunteers work in shifts to answer about 300 calls, 12 hours a day.

One bad day

Michael Avenatti, the lawyer best known for representing adult film actress Stormy Daniels, had a very bad day at the office on Thursday.

The outspoken Trump critic, who has been open about his ambitions to run for president, is taking heavy flak for an interview he gave in Time magazine.

In the piece Mr Avenatti said he believes the Democrats' 2020 nominee "better be a white male".

Pressed further, he cited the "realities of the situation" for his statement.

"I think if the Democrats nominate anyone other than a white male at the top of the ticket, they're gonna lose the election," he told the magazine.

On the same day, both Avenatti and his client Julie Swetnick (who came out with allegations against Supreme Court justice Brett Kavanaugh before his confirmation) were referred to the Department of Justice.

Senate Judiciary Chairman Chuck Grassley wrote to the FBI and Attorney General Jeff Sessions to say the pair should be investigated for making "materially false statements" to his committee.

On Twitter Mr Avenatti, who stands by his client, welcomed any investigation, declaring: "It's Christmas in October!"
