I love these pictures.

On the first day of summer (the longest day of the year) the weatherman in Chicago announced that on that day there would be 24 hours of sunshine at the North Pole. I apologize if this question has been asked before and I know it's off topic, but does that mean that instead of rising in the East and setting in the West, at the North Pole the sun would make a complete circle in the sky at some small angle above the horizon?

Thanks in advance.

Yes, exactly.

At the North Pole (90 degrees north) the axial tilt of the Earth is at its greatest extent facing the Sun on June 20/21.
The Sun will appear to circle the horizon at an angle of 23.5 degrees above the horizon there.

The opposite applies at winter solstice December 21/22.

At various latitudes, the apparent solar track is shown below for equinox and northern summer solstice..

But also your weatherman didn't give you QUITE enough information. At the North Pole you wouldn't have just 24 HOURS of daylight, you'd have 6 MONTHS of sunshine. Sunrise there is about March 21, and sunset is about September 21. Night prevails after a couple of weeks of twilight, until March comes and the first faint light appears again.

On the Arctic Circle, 67.5 degrees north latitude, June 21 is the only day the Sun stays up 24 hours. Technically. Actually, the solstice and refraction through the Earth's atmosphere combine to make the Sun appear - several days in a row - to be up 24 hours.

At this location, the Sun will be at an angle of 47 degrees above the horizon at local noon, and dip to the horizon at midnight.
