Mollie Tibbetts's father is calling on politicians to stop using his daughter as a 'pawn' to further an agenda.

The op-ed written by Rob Tibbetts was published on Saturday in the Des Moines Register the day after Donald Trump Jr wrote an op-ed for the same paper slamming liberals for downplaying the illegal alien status of her alleged killer.

'Please leave us out of your debate,' Rob wrote. 'Allow us to grieve in privacy and with dignity. At long last, show some decency. On behalf of my family and Mollie's memory, I'm imploring you to stop.'

The 20-year-old college student's body was found on August 21, one month after she was reported missing.

Cristhian Bahena Rivera, a 24-year-old illegal immigrant from Mexico, was arrested and charged with first-degree murder.

In the op-ed Rob wrote that there are politicians that have 'chosen to callously distort and corrupt Mollie's tragic death to advance a cause she vehemently opposed'.

'I encourage the debate on immigration; there is great merit in its reasonable outcome,' he continues.

'But do not appropriate Mollie's soul in advancing views she believed were profoundly racist. The act grievously extends the crime that stole Mollie from our family and is, to quote Donald Trump Jr., "heartless" and "despicable".'

He ended the piece by calling on citizens to 'build bridges, not walls.'

On Friday, Trump Jr kicked off his fiery column by writing: 'The reaction from some Democrats and others on the left to the murder of Mollie Tibbetts is as despicable as it is revealing,' he wrote.

'The mask is off and the true radical face of the Democrats has been exposed... they are seemingly more concerned with protecting their radical open-borders agenda than the lives of innocent Americans.'

The executive vice president of the Trump Organization then accused media outlets of leaving out details about Mollie' alleged killer.

'Liberal media outlets went through great pains to cover the story without actually covering the story,' he wrote.

'Instead of truthful headlines such as "Illegal immigrant arrested in connection with murder of Mollie Tibbetts", multiple outlets ran headlines such as "Man arrested in connection to disappearance of Mollie Tibbetts".

'They don't want you to know what happened to her - and they certainly don't want you to know who is responsible.'

He further reprimanded US Senator Elizabeth Warren, who he said 'played down the killing and said the focus should be on the "real problems" of our immigration system, such as the separation of families at our border.'

Warren, however, said in a statement on CNN: 'I'm so sorry for the family here, and I know this is hard not only for her family, but for people in her community, the people throughout Iowa. But one of the things we have to remember is we need an immigration system that is effective, that focuses on where real problems are.'

Trump Jr also called out a few journalists in the column - who he slammed for their remarks regarding the college student's death.

He said the most outlandish comment came from Chris Riotta, a writer for The Independent.

The victim's cousin, Sam Lucas, (pictured on Twitter) slammed conservatives for using the 20-year-old college student's murder as 'political propaganda' in wake of killer's arrest

Riotta 'claimed in the Independent that "Russian bots used Mollie Tibbetts' death to distract from Michael Cohen and Paul Manafort,"' Trump Jr. wrote.

'Riotta and his ilk simply can't face the fact that the murder of an innocent girl at the hands of an illegal alien is news that Americans actually care about.'

Aside from the Trump family, other conservatives, including commentator Candace Owen, tweeted asking what leftists would do for the victim after they 'cried when illegal immigrants were temporarily separated from their parents.'

Mollie's cousin, Sam Lucas, lashed out at Owen in a series of explosive tweets last Wednesday.

The victim's cousin said Owen was using the college student's murder as political propaganda.

'We are not so f**king small-minded that we generalize a whole population based on some bad individuals. Now stop being a f**king snake and using my cousin's death as political propaganda. Take her name out of your mouth,' Lucas wrote on Twitter.

'And fyi @RealCandaceO, my whole family is hurting right now and you're not helping.

'You're despicable and this is so far from the loving and kind soul that Mollie was. My prayers go out to you in hopes that maybe you'll become a better person. Not hedging my bets tho.'

Lucas later clarified that she didn't speak for the whole Tibbetts family - and was only trying to argue that they should be able to grieve without politics

The Mexican national charged over Mollie's death had been living in Iowa and, according to cops and the government, had been working illegally for anywhere between four and seven years, police said.

He was arrested and charged in her death after recently recovered surveillance footage led police to his Chevy Malibu following a month-long investigation into Mollie's disappearance.
