President Barack Obama will be in Atlanta on Tuesday to attend fundraisers for his re-election campaign, including a reception at the Westin Peachtree Plaza Hotel downtown.

The president is expected to arrive at Hartsfield-Jackson International Airport late morning and to leave from there early afternoon.

Obama reportedly will also make a stop at the set of a movie filming this week in Midtown and Inman Park, according to The Buzz.

Obama's visit is expected to affect traffic. The Secret Service keeps all routes secret, but rolling roadblocks may take place Tuesday afternoon on Atlanta-area interstates. Traffic may be affected near the fundraisers and the set of the movie.

The movie "42" is about baseball great Jackie Robinson, who broke Major League Baseball's color line by joining the Dodgers in 1947. The movie, which has been filming in Birmingham, Chattanooga and Macon, is wrapping up with some background scenes in Atlanta.
