Heading out and hitting the campaign trail in an area that is home to one of the most critical issues in the next election cycle, former President Donald Trump will visit the U.S.-Mexico border on Sunday, as CBS News reports.

While there, Trump will unveil a series of sweeping immigration rules he intends to implement if he secures another term in the Oval Office.

Trump heads south

The campaign event for Trump is slated for the small town of Edinburg, situated in the Rio Grande Valley, an area in which illegal border crossings have been especially high.

Republicans have seen recent successes in the locale in terms of outreach to the largely Hispanic population living there, and Trump's appearance likely aims to build on that momentum.

As CBS News notes, Trump has been particularly outspoken in recent weeks on the topic of illegal immigration, and he has begun outlining the steps he would take to curb the crisis if elected next November.

Known for the hardline immigration policies implemented during his term in office, including new asylum restrictions, border wall construction, and more, Trump is hinting that he is prepared to take additional steps that could include a massive deportation initiative, an end to birthright citizenship, and other actions sure to provoke outrage on the left.

Abbott on board

Also expected as part of Trump's Sunday campaign event is an announcement of Texas Gov. Greg Abbott's endorsement of the former president for the 2024 GOP nomination, as Fox News reports.

Abbott's appearance will include his annual pre-Thanksgiving distribution of tamales to National Guard members and Texas Department of Public Safety personnel working along the border as part of what is known as Operation Lone Star.

Trump and Abbott have had a mutually beneficial relationship over the years, with the former president having endorsed the Texas governor in his 2021 reelection battle.

Insiders have indicated that Abbott viewed Trump's support as a key part of his success in the last cycle and that he now likely feels compelled to reciprocate ahead of the 2024 presidential election.

Immigration takes center stage

The joint appearance by Trump and Abbott is shining a spotlight on what is expected to be a highly contentious issue in the presidential race yet to come.

Criticism of President Joe Biden's border policies and the perceived failings of Department of Homeland Security Secretary Alejandro Mayorkas has been at the forefront of debate almost since the beginning of the current president's term in office.

Trump's promises of a crackdown that may include reinstatement of travel bans along with his “Remain in Mexico” program – among other pledges – have been described by the Biden camp as “scary,” but whether voters in large numbers agree with that assessment remains an open question.

Sunday's high-profile event with Abbott – who has taken decisive and sometimes controversial actions within his own state to stem the tide of illegal immigration – will underscore the stark differences in this realm between Trump and Biden, the two men who appear – at least right now – destined for a rematch next fall.
