The Trump campaign has officially begun the process of requesting information from a small number of potential running mates, indicating a significant escalation in the search for a vice presidential candidate, according to sources. Among those asked to provide vetting paperwork are North Dakota Governor Doug Burgum, Senators Marco Rubio and J.D. Vance, as well as Senator Tim Scott, Representatives Byron Donalds and Elise Stefanik, and former Secretary of Housing and Urban Development Ben Carson.

These initial requests are believed to reflect the individuals who currently top Trump's list of potential vice presidential candidates. However, campaign officials have made it clear that the final decision rests with former President Donald Trump himself.

Brian Hughes, a senior adviser for the Trump campaign, emphasized that speculation about Trump's choice is baseless unless it comes directly from Trump. The former president has stated that he plans to announce his decision closer to the Republican National Convention in July.

In recent weeks, those being considered for the vice presidential role have increased their public presence by defending Trump during his hush-money trial and making appearances on cable networks. Governor Burgum notably appeared alongside Trump and his son, Donald Trump Jr., during the jury deliberations, shortly before Trump's conviction.

While the potential contenders, including Burgum, Rubio, and Vance, have avoided directly addressing the possibility of becoming Trump's running mate, they have expressed willingness to do whatever is asked by the Trump campaign. This has included serving as campaign surrogates and fundraising for Trump's campaign.

There have been discussions within the Rubio camp regarding potential constitutional issues arising from having both the presidential and vice presidential candidates from the same state. It is speculated that Rubio may consider relocating to address this concern.

As the vetting process continues, the requests for information from potential candidates indicate a significant advancement in the selection of a vice presidential candidate for Donald Trump. Only time will tell who ultimately gets chosen for the coveted role.
