Washington (CNN) President Donald Trump roiled some of his top allies in Congress this week with a surprise withdrawal from northern Syria.

The move earned a rare chorus of criticism from Republicans like Mitch McConnell, Lindsey Graham and others. McConnell urged Trump to reconsider on Monday, noting that "American interests are best served by American leadership, not by retreat or withdrawal."

Despite the churn in Washington, Trump held a MAGA rally Thursday in Minneapolis -- his first since the impeachment investigation was announced last month. Trump debuted his rally-style talking points on the impeachment investigation, calling it an effort by the "Washington swamp" to "nullify the results of a truly great and democratic election." Expect to hear more of that Friday night when Trump heads to Louisiana for another rally.

Trump also attacked Joe Biden and his son Hunter from the podium -- and supporters shouted, " Lock him up ."
