The Latest on the attempt in Brazil's Congress to impeach President Dilma Rousseff (all times local):

1: 20 p.m.

Several thousand protesters are arriving in Brazil's capital ahead of an expected vote in Congress on whether to impeach Brazilian President Dilma Rousseff.

In attempts to keep things peaceful, authorities have set up a wall that traverses the esplanade in front of Congress. The wall is over a mile (kilometer) long.

Supporters of Rousseff are being directed to one side while detractors pushing for her impeachment are going to the other side.

A vote in the lower Chamber of Deputies is expected later Sunday.

Rousseff is accused of using sleight-of-hand accounting techniques to hide deficits and shore up support for her embattled government. Rousseff says she has done nothing wrong and notes she has not been charged with a crime.
