High court suspends house speaker

Cunha is the architect of the impeachment drive that is expected to force president to step down

Brazil's Supreme Court on Thursday suspended a powerful lawmaker at the center of efforts to impeach President Dilma Rousseff, on grounds he tried to obstruct a probe into his alleged corruption.

Eduardo Cunha, the speaker of Brazil's lower house of Congress, is the architect of the impeachment drive that is expected to force Rousseff to step aside from office on Wednesday.
