Danny Page, an independent candidate for the U.S. Senate, has filed two more complaints against Alexander, whom he accuses of "colluding" with the Tennessee State Museum to boost the federal lawmaker's candidacy.
The latest complaints were filed with the Senate Ethics Committee and the Tennessee Ethics Commission, Page said.
Last month, Page filed a complaint with the Federal Election Commission, citing 2013 news reports that Alexander supporters sought to set up a traveling exhibition on Alexander during the 2014 election year.
State museum officials later backed off the planned exhibit of Alexander, a former governor, U.S. Education Secretary and two-time GOP presidential candidate. The exhibition, which was to be paid for out of privately raised funds, was delayed until 2015.
An Alexander spokesman, Brian Reisinger, has previously called Page's statements a "silly political stretch" and also stated said the "complaint is about a traveling exhibit that never traveled."
Page is one of several independent candidates running in the Nov. 4 general election.
