how many at trump rally last night

Trump said at least 45,000 people were at the rally he described, but that figure was his own estimate and was not independently verified in the reporting I found. The event coverage I found was about his Great American State Fair / Fourth of July rally context, not a separate official attendance count.

What’s known

• Trump’s quoted claim: at least 45,000 attendees.

• No independent attendance number was provided in the sources I found.

• News coverage described the crowd as large and cheering, but did not confirm a precise official total.

Bottom line

If you mean the rally Trump was talking about last night, the best available number is about 45,000 by Trump’s estimate.
