In 2020, Mr Cruz was among the top 20 recipients of
oil and gas money in the Senate. He was given $124,272 by the industry that year.
Much more telling, however, is that in 2018 - an election year for Mr Cruz - he was the top recipient of oil and gas money in the Senate, receiving nearly $800,000 from the industry.
Over the course of his career, Mr Cruz has received a total of $3,770,950 from oil and gas interests.

Mr Cruz is one of numerous Texan politicians to receive massive amounts of money to represent the oil and gas industry in Congress.
Texas Governor Greg Abbott has raked in an enormous $150m in oil and gas donations over the past six years, more than any other US governor.
Between Sen. John Cornyn, Rep. Dan Crenshaw, and Mr Cruz, the three have collectively received more than $1m in industry donations.
The influence of oil and gas may have influenced some Texan politicians' attempts to shift blame for the widespread power outages on wind turbines.
