WASHINGTON, D.C. (AP) – Crowds on the National Mall — where people without tickets can watch the inauguration — are growing steadily.

But just about an hour before the swearing-in there are still wide swaths of empty space. Some people were prevented by security barriers from getting closer to the Capitol despite having plenty of space in front of them.

The grass on the Mall was protected by white plastic and there were some muddy spots amid intermittent rain.

Hillary Clinton has arrived for the inauguration of the man who defeated her in the bitter presidential contest.

Clinton is at the Capitol with her husband, former President Bill Clinton.

Trump and Clinton were last face to face at a charity dinner in New York in October.

The Democratic nominee and former secretary of state waved to reporters when she arrived for the ceremony this morning, but she’s not answering questions.

Most of the Donald Trump backers who are walking to the inauguration past Union Station in Washington are trying to ignore protesters outside the train station.

One man, Doug Rahm of Philadelphia, however, engaged in a lengthy and sometimes profane yelling match with protesters.

“Get a job,” Rahm said. “Stop crying snowflakes, Trump won.”
