Two weeks before the midterm elections, President Donald Trump is coming to Indianapolis to give the keynote address at a national convention.

Trump is expected to speak in front of thousands of members of the National FFA Organization.

Here's what we know about the president's visit:

Why is Donald Trump coming to Indianapolis?

President Trump is coming to Indianapolis to speak to the 91st Annual Future Farmers of America Convention and Expo, according to a White House official.

The event is an annual convention for the National FFA Organization, commonly known as the FFA.

What is FFA?

Though the organization has changed its official name, FFA stands for Future Farmers of America. The organization has more than half a million members in high schools throughout the country, according to its website.

FFA members are known for their blue corduroy jackets, and they use the organization to learn about leadership and agriculture.

Can I get a ticket to see Trump in Indianapolis?

No. President Trump will be speaking at Bankers Life Fieldhouse as part of the FFA convention, which is limited to members of the organization.

Attendees will be FFA Convention badge-holders who received one of 7,000 tickets handed out by the organization on a first come, first served basis Thursday.

For those who can't make it inside the building, the speech will be streamed on FFA.org.

Agriculture Secretary Sonny Perdue is expected to attend with the president.

Will Trump's visit disrupt traffic?

It's likely that the president's visit and the security precautions around it — combined with the tens of thousands of out-of-towners here for the convention at which he's speaking — will create traffic problems around Downtown Indianapolis.

Early Friday afternoon, the Indianapolis Metropolitan Police Department announced some expected closures.

Between 6 a.m. and 5 p.m. Saturday, IMPD said Delaware and Pennsylvania streets will be closed to through traffic between Maryland and South streets — essentially the blocks immediately surrounding Bankers Life Fieldhouse.

Between 1 and 5 p.m., there will also be "temporary street closures" from the airport to Bankers Life, though police did not specify which streets would close. Police said the closures will last about 30 minutes at a time and will be spread out from the time Air Force One lands until the time the president leaves.

Specific details on Trump's route to the arena are not available, so it will be difficult to predict exactly which areas to avoid and when.

In general, the best decision may be to stay away from the Downtown area Saturday unless you're coming to the convention. If you need to travel Downtown, give yourself extra time.

What will Trump talk about in front of FFA students?

Trump's speech comes less than two weeks before the midterm elections on Nov. 6, when Democrats and Republicans will battle for control of Congress. Among the most important races is the one between Indiana Democratic U.S. Senator Joe Donnelly and Republican challenger Mike Braun.

Braun is backed by Trump, who on Aug. 30 came to Evansville in support of the Republican businessman trying to unseat incumbent Donnelly.

With this race coming down to the wire in a state where agriculture is important, Trump is likely to speak about how the administration's trade dispute with China is affecting farmers' bottom lines.

But it's not unusual for Trump to stray from his script: In July 2017, Trump called for the repeal of Obamacare, praised the stock market, and mocked Barack Obama in a speech in front of a huge crowd of Boy Scouts at the group's national jamboree.
