"Her numbers have been gradually going up. There's been a lot of missteps by Trump that have helped her, but she's been moving up in the polls," Malloy said on John Catsimatidis's radio show "The Cats Roundtable." 

"There's something significant going on — this shuffling of campaign staff with Trump. There are red flags with the Trump campaign right now, there's no doubt about that," he said of the Republican presidential nominee. 

Trump's former campaign manager, Paul Manafort, recently resigned, and Trump brought on two new people — Kellyanne Conway as campaign manager and Breitbart News executive Steve Bannon as campaign CEO — to helm his bid. 

Clinton, the Democratic presidential nominee, currently leads Trump by 6 percentage points nationally, according to the RealClearPolitics polling average.
