Trump draws far smaller inaugural crowd than Obama

The Metro system also posted that only two parking lots at stations were more than 60 percent full.

The smaller crowds may prove humbling for Trump, who frequently boasted during the campaign about the attendance at his rallies and would claim, often inaccurately, that thousands more people were waiting outside and unable to get into the event.

Some Trump supporters were slowed entering the Mall due to delays at security checkpoints caused by protesters.

Thousands of people at Obama's inaugurations were also delayed due to logistical hold-ups at the security checkpoints.
