All eyes will be on Cleveland starting Monday as the Republican National Convention kicks off. Presumptive Republican nominee Donald Trump is looking for his party’s backing as the race for the White House enters its next decisive phase.

The convention runs from Monday until Thursday at the Quicken Loans Arena and a live stream will be available for free through Twitter in a deal struck with broadcaster CBS. Twitter will broadcast the CBSN digital streaming service and it will be available to anyone for free even if you do not have a Twitter account.

The convention also has an official phone app that is available for download here for iOS devices and here for Android devices. Some live streams will be available via the mobile applications. Other major TV networks will also be carrying coverage of the event.

Trump has already surpassed the 1,237 delegates needed to secure the party’s nomination. Approximately 2,470 delegates and 2,302 alternate delegates from all 50 states, the District of Columbia and five territories are expected to attend the convention that will select the Republican Party’s presidential and vice presidential nominee and aim to crystalize a party platform.

Trump has promised that the convention will be a must-watch affair and that he and members of his family will speak. If the convention follows tradition, Trump would be the last person to address the large crowd Thursday night.

“We’re going to come up with some things that will make it interesting and informative,” he said, ABC News reported.

Former presidential candidate Texas Sen. Ted Cruz is also expected to speak at the convention. Notable Republicans who will not be attending the convention include former President George W. Bush and George H. W. Bush, as well as Sen. John McCain and former Gov. Mitt Romney, the 2012 nominee.

Approximately 50,000 people are expected to visit Cleveland during the convention. This year marks the fourth time the Republican Party has held its convention in Ohio, a crucial swing state in a November general election.
