Meanwhile, Democratic presidential candidate Hillary Clinton is expected to announce her running mate this week, ahead of the Democratic National Convention in Philadelphia next week. Some of the people on her short list reportedly include Virginia Senator Tim Kaine, Colorado Governor John Hickenlooper, U.S. Secretary of Agriculture Tom Vilsack and Secretary of Housing and Urban Development Julián Castro. Clinton also met with Massachusetts Senator Elizabeth Warren on Friday, although many are speculating Warren will not be chosen as Clinton’s running mate, because she’s been asked to speak on the first night of the DNC. Running mates usually speak later in the conventions.
