From the Mueller Report:
Intrusions Targeting the Administration of U.S. Elections
In addition to targeting individuals involved in the Clinton Campaign, GRU officers also targeted individuals and entities involved in the administration of the elections. Victims included U.S. state and local entities, such as state boards of elections (SBOEs), secretaries of state, and county governments, as well as individuals who worked for those entities.186 The GRU also targeted private technology firms responsible for manufacturing and administering election-related software and hardware, such as voter registration software and electronic polling stations.187 The GRU continued to target these victims through the elections in November 2016. While the investigation identified evidence that the GRU targeted these individuals and entities, the Office did not investigate further. The Office did not, for instance, obtain or examine servers or other relevant items belonging to these victims. The Office understands that the FBI, the U.S.
Department of Homeland Security, and the states have separately investigated that activity. By at least the summer of 2016, GRU officers sought access to state and local computer networks by exploiting known software vulnerabilities on websites of state and local governmental
entities. GRU officers, for example, targeted state and local databases of registered voters using a technique known as “SQL injection,” by which malicious code was sent to the state or local website in order to run commands (such as exfiltrating the database contents).
It's not that Russia did not try to cyber attack the US's voting hardware during the time Obama asked it to be looked into.
Trump's own intel Director John Radcliff came to the same conclusion of Russia's effort.
The Bipartisan Senate Intel committee led by Sen Marco Rubio came to the same conclusion.
They weren't successful.
Gabbi is just doing what GOP House leader Mike Johnson is doing by canceling all votes till Sept. Throw shade for Trump.
