With his eyes firmly on the November election, Donald Trump will Friday become the first US president to address in person the country’s biggest annual gathering of anti-abortion campaigners.

Addressing a crowd of thousands on the National Mall in Washington, Trump is assured of a hero’s welcome as the unrivaled star of this year’s “March for Life.”

While impeachment will forever stain his record, Trump is all-but-assured of exoneration by the Republican-held Senate and the former real estate magnate is already looking past the trial to the re-election fight that awaits.

Before entering politics Trump described himself as pro-abortion rights, but he has increasingly aligned himself with the anti-abortion movement as he works to firm up his electoral base — none more so than the white evangelicals who backed him overwhelmingly in 2016.

“We are proud to stand with President Trump and are going all in to ensure his re-election,” said the activist, whose group plans to visit four million voters before election day “to defeat abortion extremists.”

The “March for Life,” which Trump has addressed by video message the last two years, is organized annually on or near the anniversary of the Supreme Court’s ruling in Roe v Wade, which legalized the procedure nationwide on January 22, 1973.
