Trump to visit Pennsylvania truck plant

The appearance marks his first major public event outside Washington since an interim agreement ended the Iran conflict that began February 28. The visit is his fifth to Pennsylvania during his second term. The Macungie plant lies in a district where Republican Representative Ryan Mackenzie faces Democratic challenger Bob Brooks in November.

Economic and political context A June Associated Press-NORC poll found that about one-third of U.S. adults approve of the president's handling of the economy, unchanged from the prior month. The same survey showed 65 percent disapprove of his approach to Iran.

Gasoline prices rose after the Iran conflict, a development the administration seeks to move past before the midterm elections. Republicans currently hold a narrow House majority, and the outcome in districts such as the 7th could affect the president's remaining two years in office.
