A local Republican election official in Michigan has promised to certify the results of the November presidential election.

Rep. Matt Maddock's comments came days after Republican presidential nominee Donald Trump said people who cheat in elections will be prosecuted.

In a terse order, the Michigan Supreme Court refused to overturn a ruling from the Michigan Court of Appeals, rejecting appeals filed by an attorney.

Robert F. Kennedy Jr. had ended his presidential campaign and endorsed Donald J. Trump last month. His presence on the ballot could be significant in the crucial battleground state.

Kennedy will remain on Michigan's ballot in November despite ending his presidential campaign and endorsing Trump.

The Michigan Supreme Court ruled on Monday that Robert F. Kennedy Jr.'s name will remain as a presidential candidate on the state's ballots for the Nov. 5 election, despite his request to be removed,

The court vacated the state Appeals Court ruling, concluding that Kennedy did not show "an entitlement to this extraordinary relief."

LANSING, Mich. -- The highest courts in two states ruled differently Monday on efforts by Robert F. Kennedy Jr. to be removed from their presidential ballots, with a divided North Carolina Supreme Court affirming he should be omitted and the Michigan Supreme Court reversing a lower court decision and keeping him on.

Michigan's effort is the most aggressive of its kind among the key battleground states and aims to protect against a vulnerability Trump and his allies exposed nearly four years ago.
