Failed presidential candidate Senator Ted Cruz is stepping back into the national spotlight at the Republican National Convention for Donald Trump, the soon to be official presidential nominee. Cruz’s “burying the hatchet” speech will be a pivotal moment for the Republican Party in 2016.

The Texas senator is widely expected to make another run for the White House in 2020 if the GOP loses to Hillary Clinton in 2016. Cruz finished second to Trump in the 2016 race, and associates in Cleveland are already seeking rule changes in the next primary that might aid him.

“Sen. Cruz’s speech will be viewed by many, if not all, through the lens of him being a potential candidate,” said Charlie Gerow, a GOP communications strategist. “I think he chose wisely to go to Cleveland and to showcase his abilities and his views for the party’s future.”

Republicans anticipate Cruz will say nice things about Trump during his speech. Trump extended an invitation to Cruz for a speaking role in a gesture of party unity.

Cruz has shed some light on what he’ll discuss. He said after meeting with Trump in Washington that he would emphasize the country needs to change direction.

“I’m going to urge Americans to get back to the Constitution to change the path we’re on: eight failed years of the Obama-Clinton economy; eight failed years of a presidency disregarding the Constitution and Bill of Rights,” he told reporters. “Eight failed years of a commander in chief not protecting Americans and keeping us safe from radical Islamic terrorism. It’s time for that to end.”
