"Even holding conferences or events at Trump properties will be a problem for large publicly traded companies, or companies that provide a direct to consumer product", she said.
Cassidy, 63 and a physician, had initially sided with the vast majority of Senate Republicans who voted last month to block the trial from moving forward. He stressed that while Congress has exhausted its avenues for punishing Trump, the United States justice system has not.
A guilty vote by McConnell, which likely would have brought some other Republicans along with him, would have marked a more direct effort to wrest the party away from Trump.
CNN's Jim Acosta reported on some of the reactions within former President Donald Trump's inner circle to his acquittal in his second impeachment trial, quoting one unnamed Trump adviser as saying that "the devil is a saint when compared to Donald Trump".
However, Mr Trump's lawyer, Michael van der Veen, called the proceedings a "show trial" and said the Democrats were "obsessed" with impeaching Mr Trump.

The managers proved in devastating detail that Trump incited the January 6 riot, not only in his inflammatory speech that day, but also in his long and duplicitous campaign to discredit the election and cling to power.
After his acquittal, Mr Trump released a statement denouncing the trial as "the greatest witch hunt in history".
McConnell had also told associates he thought Trump perpetrated impeachable offences and saw the moment as a chance to distance the Republicans from the damage the tumultuous Trump could inflict on it, a Republican strategist told The Associated Press at the time, speaking on condition of anonymity to describe private conversations.
Herrera Beutler ended her statement Friday by challenging those with firsthand knowledge of Trump's actions during the Capitol siege - including former Vice President Mike Pence - to come forward. "Even those opposed to the conviction, like Senate Minority Leader McConnell, believe Donald Trump was guilty of a "disgraceful dereliction of duty" and "practically and morally responsible for provoking" the violence unleashed on the Capitol".
The visceral, bloody images from that day were at the core of Democrats impeachment case against Trump.
"He summoned his supporters to Washington... whipped them into a frenzy, and directed them at the Capitol", Senate Majority Leader Chuck Schumer said after the vote.
